Actually, there should not be any problems with the usual character sets. But there are Gedcom files with unusual character set names or with a character set information which is simply wrong because it does not match the used character set. The dialog for the qualified selection of the character set will help you. This dialog opens automatically if no character set or an unusual character set is used in the CHAR tag in the Gedcom file. This dialog does not open automatically, though, if a usual character set is used in the CHAR tag, that is incorrect for the current Gedcom file. In those cases you can force the opening of the dialog: Gedcom Options, Import Options tab, mark the Always display the character set selection dialog checkbox.

In the manual in the Dialogs, Gedcom Options, Preferred Given Name Coding section, there are several examples with pictures which show the procedure step by step.

In the manual in the Dialogs, Gedcom Options, Preferred Given Name Coding, Married Name Coding and Marriage Data Coding sections there are several examples with pictures which show the procedure step by step. The setup of the further Codings is done according to the same principle.

Have you tested all options while exporting the Gedcom file in your genealogy program? If all tests fail, use the personal support of the FamilyTreeFactory. You find a function in the Help/Info menu for the preparation of an Email Support Query. Enclose your Gedcom file with the email; personal data will of course be kept confidentially. The Gedcom file will be analyzed and it will be detected why it cannot be opened in the FamilyTreeFactory. Depending on the analysis results a solution is suggested or perhaps the program capabilities will be extended.

At first set everything in the Treeview Options dialog, Box Content, Box Font and Box Format tabs as you would like. Go to the Automatic Width/Height tab, mark the Use Automatic Width/Height function checkbox and select the aim using the Width/height ratio of the graphic radio button. Deactivate the Use settings from Printer Page checkbox and enter an unrealistic Set Width/Height Ratio, e. g. 1 %. Deactivate both checkboxes Avoid text breaks in names and Avoid text breaks in other text.
 
Reactivate possibly deactivated dialogs (Tools menu, Reactivate deactivated Dialogs) to get all messages in the next step.
 
Create the graphic once more. Now the Automatic Width/Height function will try unsuccessfully to dimension the graphic so that the width makes up only 1% of the height. The result is, however, the narrowest graphic which can be achieved with the settings for Box Content, Box Font and Box Format.
 
You will get a message that the Automatic Width/Height function can not create the graphic with a small enough width. This message points to the causing person box and to the one word in this box, that can not be wrapped. This person box is marked and centered if you click on the appropriate button. With a double-click on this person box the Personal Data dialog will open, where you can edit the long word to make it wrappable by inserting a hyphen. However, this method cannot be recommended for names, and possibly a similar long word will be found next time.

At first set everything in the Treeview Options dialog, Box Content, Box Font and Box Format tabs as you would like. Do not mark the checkbox Equal box heights in all generations on the Box Format tab to ensure, that the smallest box height will be calculated separately for each generation. Go to the Automatic Width/Height tab, mark the Use Automatic Width/Height function checkbox and select the aim using the Width/height ratio of the graphic radio button. Mark both checkboxes Avoid text breaks in names and Avoid text breaks in other text.
 
Now create the graphic once more. The result is a graphic with minimal height which can be achieved with the settings for Box Content, Box Font and Box Format.
 
You may reduce the content of the person boxes in the Box Content tab to get a lower graphic. There is an extreme compact form for the output of some event dates (date of birth or baptism, date of death or burial) in a single line: If the output of the places of birth, baptism, death and burial is deactivated and if the output of the cause of death is deactivated and if the date format is YYYY and if the date of birth or baptism as well as the date of death or burial are saved, the output of the living dates will be in the form "YYYY - YYYY", e. g. "1856 - 1941".

Go to the Treeview Options, Graphic Format tab. In the area Symbol Key and Titles is a Font Color... button.

You can change only the words in the output language file FamilyTreeFactory.lng from which the main title is produced automatically. Use the Output Language File Editor in the Tools menu.
 
You can, however, deactivate the main title in the Treeview Options, Graphic Title tab, and then use the sub-title alone with any text. Use the font settings and the orientation too.
 
Furthermore you can deactivate the sub-title and use one or several Free Placeable Text, Image and Geo Objects to create your own title. The creation of a Free Text Object with a graphic title is very easy by drawing a rectangle on the desired area of the treeview with your left mouse button while holding the Ctrl key. Select the option Create Text Object 'Graphic Title'... from the menu that appears. The created Text Object includes text variables to output the main title mentioned above; changes and additions can be made in the dialog Edit Free Text Objects.

Other languages can be defined in the output language file FamilyTreeFactory.lng using the Output Language File Editor in the Tools menu.
 
If you defined a new language please share it with other users. Send your output language file to info@familytreefactory.com to be published with the next version.

The Free Placeable Text, Image and Geo Objects (Treeview menu) make an individual design possible in addition to the automatically created graphic. Use Free Text Objects for your own titles and explanations or for whole family chronicles. Use Free Image Objects for specifically placed background pictures, coat of arms from all epochs, maps with the places of origin or group photos with members of the family. Use Free Geo Objects for emphases, special connection lines or for ornaments.
 
Arbitrarily many Free Objects can be created. The most comfortable way is to drag a rectangle with the mouse while pressing the Ctrl key; the rest is done intuitively in the dialogs. Extensive texts should better be prepared in an external editor and then copied into the editor of the Edit Free Text Objects (right mouse button, Paste).
 
Every Free Object forms a layer of its own in the graphic. If objects are overlapping, the higher layer paints over the lower layer. You find details to the layer model of the FamilyTreeFactory in the appendix to the manual.
 
Use column and row numbers, a person index and duplicate connection lines (Treeview menu), so that a spectator finds big graphics more understandable.
 
Create a card index with all saved personal data, also those which are not shown in the person boxes for space reasons (Personal Data menu, Export Card Index As PDF File...). A card index can also be included during export of a graphic into a PDF document (Treeview menu, Export Treeview As PDF File...).

The mbox-columns and mbox-rows (speak milli-box...) are a scale for the position of the Free Placeable Text, Image and Geo Objects. The scale is the columns and rows grid of the graphic. Through anchorage in this grid no new positioning and dimensioning of the Free Objects is required if the measurements of the person boxes and with that the complete graphic are changed.
 
The grid is outlined here in the example of an ancestor tree:

If unequal box heights were adjusted in different generations, there is no more uniform scale between the actual position in the graphic and the row grid. Expressed mathematically: The function is still continuous, but not continuous linear, but only in sections linear. However, the anchorage of the objects at the columns and row grid is ensured independently of this.

Schematic depiction of the mbox-column and mbox-row grid at unequal box heights:

At unequal box heights, the calculation of mbox-rows in large top or bottom graphic margins  (mbox-rows < 0 und mbox-rows > max. row no. * 1000) is based on the maximum box height existing in the graphic.

Set the following Treeview Options:
 
• Printer Page tab: Click on the Printer Setup... button, select the printer, set its properties including the paper size and close the dialog. Set Landscape or Portrait and the number of pages horizontal und vertical as required. Select the orientation Use paper format for size. Set Optional Margins as required.
 
• Automatic Width/Height tab: Switch on the Automatic Width/Height using the Use Automatic Width/Height function checkbox, select the aim using the Width/height ratio of the graphic radio button, and mark the Use settings from Printer Page checkbox.
 
Reactivate perhaps deactivated dialogs (Tools menu, Reactivate deactivated Dialogs) to get all messages in the next step.
 
Now create the graphic once more. In any case you receive a graphic which, in the best possible way, uses the set paper size. It can happen that the Automatic Width/Height function cannot make the graphic narrow (or wide) enough to match the width/height ratio of the paper size (you will get a detailed message); then you can set the paper size wider (or narrower) or increase (or decrease) the number of pages next to each other and repeat the process. Checking the results is easily possible in the Print Preview (File menu) with the Margins checkbox marked.

If you want to print a bigger graphic on several pages put together, it will usually happen that the paper cutting lines split some person boxes. If you want to avoid this, proceed as follows:
 
In the Tools menu open the Treeview Options dialog, Printer Page tab: Mark the Print at top left radio button in the area Print Justification. Click on the Don't Split Boxes button. Now the number of pages, the print overlaps and the optional margins are adjusted so that the paper cutting lines lie between the person boxes. Do not change any options after this operation, close the dialog with OK, causing the graphic to be created again. Look at the result in the Print Preview (File menu); in the print preview use the Page no. and Margins checkboxes and the Info... button to get exact information.
 
If you are satisfied with the result, close the print preview and print the graphic. Between the Don't Split Boxes function and the printing absolutely no options may be changed! If corrections are necessary the Don't Split Boxes function must be called again before printing!
 
If the print overlapping is at least 0.2 inch, the page numbers are printed on the overlapped margins, so that you keep the control while glueing them together. You glue from above on the left to the bottom on the right (as in the case of reading).
 
Moving the graphic on the total paper size caused different margins (distances to the 4 paper edges), that you probably want to cut off. To make this easier, you should print a graphic frame as a cutting line. A gray, narrow line suffices: Tools menu, Treeview Options, Graphic Format tab, area Graphic Frame, mark the On checkbox, set width to 0.01 inch, select the Color radio button and set the color to gray.

After creating a graphic you can find the measurements in the status bar below: Width and height, area and the width/height ratio. If the status bar is too short to show all information, lead the mouse pointer to the right end of the status bar whereupon a hint will be opened containing all values.
 
In addition, you can use the Current Treeview Properties... function in the Treeview menu to get all the information.
 
In addition, you can click on the Info... button in the print preview (File menu, Print Preview) opening an information window with complete information about the measurements.
 
Note: With the print justification Use paper format for size you can print every arbitrarily big graphic on any arbitrary paper size. The size of the graphic is adapted to the paper size but the width/height ratio of the graphic remains unchanged. The resulting size change factor and the resulting font size are also shown in the information window of the print preview; the size change factor is the relation of the printed size to the size which is shown on the status bar (which would be printed if not the justification Use paper format for size has been selected).

The print preview offers a complete picture (File menu, Print Preview). You can simulate the print on a large format printer by selecting so many pages horizontal and vertical in the Treeview Options, Printer Page tab, that you get an arbitrary large format. If you select for example US Letter landscape format with 4 pages vertical, you have a height of 34 inch, which corresponds approximately to the 36 inch roll at large format printers. Or if you select US Letter portrait format with 2 pages vertical, you have a height of 22 inch, which corresponds approximately to the 24 inch roll. The number of pages horizontally can be selected similarly according to the roll paper length to be simulated. Create a graphic with this paper size and get a precise selection of the complete print by printing only a single page: Go to the print preview, mark the Page no. checkbox, memorize a page number with a lot of person boxes, close the print preview, start Print and select the memorized page number to print only this single page. If a good print quality was selected in the printer properties, you get a piece of what the large format printer will print.

This cannot be answered in general. It depends very much on the font but also on the visual acuity of the spectators.
 
Try in a word processing program, in which size which font is still readable for you: Write several paragraphs with the same text and assign different font sizes to every paragraph in the range of 5 to 12 points. Write to the end of every paragraph, which font size you assigned to it.
 
Copy the group of paragraphs, paste this group repeatedly at the end of the document and assign other fonts to the additional groups.
 
Print the document on a normal office printer in the highest print quality. Be careful that the printer does not scale, that is the size is not changed. Judge now which font in which font size is still readable for you.
 
In the FamilyTreeFactory you state the expected font size as follows:
 
• If in the Treeview Options, Printer Page tab, the print justification Use paper format for size is selected: Open the print preview (File menu) and click on the Info... button.
 
• If in the Treeview Options, Printer Page tab, the print justification Use paper format for size is not selected: Because the size of the graphic is not changed, the font size is not changed either. The font size is selected in the Treeview Options, Box Font tab.
 
Take into account that in the Treeview Options, Box Font tab, for the output of the names perhaps an extension of the font size has been entered.

The printer drivers for normal office printers for the home and office area are not always able, as experience shows, to print a large number of large image files. It can happen that instead of an image only a black area is printed or that not all pages are printed. Detailed tests have shown that these errors are not due to the output of the FamilyTreeFactory but inadequate graphic resources of the drivers.
 
The following actions can help completely or partially:
 
• Use the free, universal PostScript printer driver "AdobePS" for the usually PostScript-capable laser printers which worked best at all tests with the FamilyTreeFactory.
 
• Do not select any unnecessarily high resolution in the printer properties. Depending on the printer model you can establish only a low or not the slightest difference between 300, 600 or 1200 pixels per inch in the result. You can check the selected printer resolution in the FamilyTreeFactory: Help/Info menu, Printer and Monitor Info... shows information about the printer and about the monitor.
 
• Try to replace JPEG image files *.jpg and *.jpeg by bitmaps *.bmp. Through this the resources of the printer driver get less loaded per image, because all image formats are converted to bitmaps before the output and this conversion uses up resources. It also can be, though, that the printer driver saves the original image files intermediately as several images which increases the load of resources again.
 
• If you want to print a graphic on several pages, divide the work into several print jobs. In the print dialog you can indicate the pages to be printed, for example in the first print job page 1 to 4 and in the second print job page 5 to 8.
 
• Do not print directly but direct the output to a file *.prn in the print dialog and copy this file to the printer port. Experiences have shown that sometimes less or no more errors at all appear this way. For copying the file to the printer port use the prompt: Start > All Programs > Accessories > Command Prompt. There you enter for example: “Copy D:\path\printfile.PRN LPT1:” and Enter. Instead of LPT1:, of course you also can indicate every other printer port like USB001 for example.
 
For all printer activities with many large image files you must be patient; if you assume the computer froze, then look to the LED for the disk access. As long as this flickers from time to time, it is still working!

Laser printers often use PostScript drivers with an option to substitute the fonts. If such an option is activated the driver substitutes the symbol font "Genealog-Symbols" by any standard font and the symbols are printed incorrectly as characters of the same code. For example the symbol for baptism (wide double wave, Code 0199) is substituted by the uppercase character "C with cedille". To avoid the font substitution deactivate the appropriate option in the PostScript driver. If your old driver does not have this option, try to get a new driver from the printer manufacturer or use the neutral AdobePS driver.

In the printshop PDF files are perhaps not printed directly out of an Adobe program but pre-processed and printed using a RIP program. At the RIP of PDF files it was observed occasionally that the family tree symbols were lost although the symbol font is embedded in the PDF file. This is a problem of the used RIP software which can be avoided as follows: Open the PDF file in Adobe Acrobat, save it as an EPS file and use this EPS file for the RIP. Every print shop should have the program Adobe Acrobat (don't mistake Adobe Acrobat and Adobe Reader!), and every print shop employee, who handles a RIP program, should be familiar with Adobe Acrobat and EPS files.

PLT files (plot files *.plt) save the data stream for the plotter control. They are used if the plotter is not attached directly to the computer. Only the plot file is then sent to the plotter without further processing. Because of the usual inkjet technology today plotters are named "large format printer", abbreviated LFP.
 
Procedure: First of all you must find a large format printer which you can use e.g. in a print shop or in the design division of an industrial company. For this large format printer you must install the printer driver on your computer; you get the driver either from the operator of the large format printer or from the web site of the manufacturer (then you need the exact type of the large format printer). Windows only needs the driver; the accompanying printer does not have to be attached! After the installation of the driver you activate the large format printer in the FamilyTreeFactory (File menu, Printer Setup...) and select a paper size which matches the graphic which you want to print. As a rule, you must setup a "user-defined" paper size with the dimensions of the graphic that you can see in the status bar of the FamilyTreeFactory, for example width 120 inch and height 32 inch. After you have completed the printer setup, create the graphic once again. To ensure that the graphic fits the paper format optimally you should switch on the Automatic Width/Height function (Tools menu, Treeview Options dialog, Automatic Width/Height tab, Use Automatic Width/Height function checkbox) and mark the Use settings from printer page checkbox. Then you "print" the graphic, however, select the option "print to file" in the print dialog and name the file with the extension *.plt. This file can be very big, depending on graphic size and image information several 100 MB can arise! Copy this file on an USB stick, on a ZIP disk or whatever you have at your disposal and what the operator of the large format printer can read. You can also burn a CD-R. This file is then transferred to the printer by the operator of the large format printer and printed by the printer.
 
Important note for HP DesignJet printer drivers: In the printer properties go to the Advanced tab and mark the option ...In computer in the area Process document.... Otherwise it can happen, particularly at bigger graphics, that the PLT file is useless; with the option ...In printer print instructions are written into the file, which have to be converted to pixel values inside the printer requiring sufficient RAM. Since the printer, however, is not attached at the PLT file generation, neither an examination of the RAM can be done nor a bottleneck can be reported.
 
It is advisable to print a little test graphic before the first large and expensive printout. This test graphic should contain all elements such as photos to check the printer driver properties. Discuss your plan with the operator of the large format printer and ask for the suitable driver properties. By the way, most printshops have so-called Viewers with which they can check the content of a plot file. This is the last opportunity to avoid an expensive misprint.

A complete graphic is saved by combining 2 files: An underlying family file (*.fml) saves the personal data, and a treeview file (*.trv) saves structure data (e.g. positioning of the boxes), the Treeview Options and the Free Placeable Text, Image and Geo Objects.
 
A treeview file (*.trv) is always assigned to one single family file (*.fml). But a family file can be assigned to arbitrarily many treeview files since many different graphics can be created on the basis of the personal data in one family file.
 
The Program Options, Automatic Functions tab, are usually set so that treeview files (*.trv) are automatically saved with their family file (*.fml) getting automatically a name that contains the assigned family file, the tree type and the primary person.
 
In addition, the Program Options are usually set such that when opening a Family File (*.fml) the last view is restored. Through that the last saved Treeview File (*.trv) is loaded, too.
 
The Treeview menu contains some functions for saving and loading treeview files (*.trv) manually: Load Treeview Data from File..., Save Treeview Data to File and Save Treeview Data to File As.... You can use this functions to restore treeview files that you saved before. With the Save Treeview Data to File as... function you can define any file names.

The used fonts are not embedded in EMF files. If you pass on an EMF file, for the generation of which you used unusual fonts (for example the symbol font 'Genealog-Symbols' of the FamilyTreeFactory), you must provide the font files, too. For the symbol font of the FamilyTreeFactory this is the file GnlgSmbl.ttf from the installation directory of the FamilyTreeFactory. The receiver must install these fonts on his computer before he can use the EMF file correctly.

It was observed that when printing graphics with Free Image Objects in which EMF files are contained, the texts and curves from the EMF files are printed with rough steps which correspond to the pixel resolution of the monitor. Such cases occur for example if you insert a second tree in a graphic with a Free Image Object that contains the second tree as an EMF file. In addition, this problem concerns the person indexes output indirectly for which EMF files are also used.
 
Tests resulted in the following: The effect depends on the monitor resolution which was adjusted at the time of the export of the EMF file. The monitor resolution at the time of printing has no influence; the method for smoothing the monitor fonts adjusted currently has an effect when printing text, though. Printer drivers of different manufacturers had the same behavior so that the defect of EMF processing probably is due to the EMF routines of Windows.
 
Remedy: Do not print a graphic with EMF Image Objects directly but export it as a PDF file. Then print the exported PDF file.
 
For the print-out of big PDF graphics you find detailed instructions in the section Printing PDFs using large format printers.

This can happen, if in the Treeview Options, Graphic Content tab, a high number of background iamges (side by side) is selected using a very large image file. The graphic resources of the computer are overtaxed. In such cases it is advisable to create a considerably smaller copy of the image file in a picture processing program and to use this during the design time; for the final output the large file is used again to enlarge the quality. During printing such problems did not occur yet.

To show photos in the person boxes, several conditions must be fulfilled:
 
• The respective photo files have to be assigned to the persons in the Personal Data dialog. This happens by choosing an image file on the Photos tab.
 
The photo files must be saved in the main directory image files (including its subdirectories), which has to be set in the Program Options, Directories tab.
 
• The output of photos must be activated: Treeview Options, Box Content tab, Output Personal Data list, Multimedia section, mark one of the Photo on the ... checkboxes.
 
• The size of the photos in the person boxes must be provided: Treeview Options, Box Format tab, area Box Dimensions, Photo height. Set to a height of about 30 mm / 1.2 inch.
 
The graphic should then be created again so that the Automatic Width/Height function can take the photos into account.

While printing images, resolutions larger than 300 pixels per inch do not improve the visible quality. Due to this fact it suffices if your images have pixel measurements which reach this value or exceed a little bit. An example: If the printed photo height is 1.2 inch, the pixel height of the image should be at least 1.2 inch x 300 pixels/inch = 360 pixels. The pixel width results from the proportion. Of course you do not have to reach this value exactly for every single image; strive for a range of 300 to 600 pixels per inch. If you are unsure in an individual case, you rather take a higher value. Unnecessary high pixel measurements lead to an unnecessary large load of the computer resources.

Usually records for partners are created newly from an already saved person so that the relationship is included automatically. You can choose instead a partner from the stock of the available records, that is connect two saved persons as partners. Proceed as follows:
 
For one of the persons (person "A") open the Personal Data dialog, for example by double-clicking on A in the graphic. Go to the Personal Data tab, Partners and Children sub-tab.
 
Set the partnership number for A: If for example the partnership to be connected is the 3rd partnership of A, click an the Partner 3 tab. Don't click the tab of a partnership number which is already occupied, because you can not establish a further partnership under an occupied number.
 
At For the partner, this is the partnership no. [x] set the partnership number of the person to be selected as partner (person "B"): If for example the partnership to be connected is the 1st partnership of B, set to 1. Don't set to a partnership number which is already occupied, because you can not establish a further partnership under an occupied number; if applicable you get a corresponding error message.
 
Now click on the right (Partner record new [Create] or [Select...]) on the Select... button. The Select Person dialog will be opened. Select the person B and close the dialog with OK. The persons A and B are now connected with the appropriate partnership numbers. If known enter the marriage data for a marriage (date and place of marriage, and so on).

If you have inadvertently entered a wrong partnership, you can part these easily again. Proceed as follows:
 
Open the Personal Data dialog for one of the two persons (person "A"), for example by double-click on A in the graphic. Go to the Personal Data tab, Partners and Children sub-tab.
 
Select the partnership number of the person A: If for example the partnership to be parted is the 3rd partnership of A, click on the Partner 3 sub-tab. In the data fields for names you can recognize the partner und check the selection of the partnership number.
 
Now click on the right (Partner [Part...]) on the Part... button. After a confirmation request the partners will be parted. If for the parted partnership children and/or marriage data are saved, it have to be indicated in a further dialog, for which of the parted partners the children and/or marriage data should remain connected.

Usually records for children are created newly from an already saved person so that the child relationship is included automatically. You can choose instead a child from the stock of the available records, that is connect two saved persons as parent and child. Proceed for it as follows:
 
Open the Personal Data dialog for the parent (person "P"), for example by double-clicking on P in the graphic. Go to the Personal Data tab, Partners and Children sub-tab.
 
Select the partnership number for P: If for example the child to be assigned (person "C") is from the 2nd partnership of P, click on the Partner 2 sub-tab.
 
Select the child number of C: If for example C is the 4th child from the 2nd partnership, click on the Child 4 sub-tab. Don't set to a child number which is already occupied, because you can not establish a further child relationship under an occupied number.
 
Now click on the right (Child record new [Create] or [Select...]) on the Select... button. The Select Person dialog will be opened showing all saved persons without an appropriate parent. Select the person C and close the dialog with OK. The person C is now assigned to the person P as a child with the appropriate partnership and child numbers.
 
Note: If a partner is saved for P with the partnership number x, the child C is of course assigned to this second parent too.

If you have inadvertently entered a wrong child relationship, you can part these easily again. Proceed as follows:
 
Open the Personal Data dialog for a parent (person "P"), for example by double-click on P in the graphic. Go to the Personal Data tab, Partners and Children sub-tab.
 
Select the partnership number of the person P: If for example the child to be parted (person "C") is from the 3rd partnership of P, click on the Partner 3 sub-tab.
 
Select the child number of C: If for example C is the 4th child from the 3rd partnership, click on the Child 4 sub-tab. In the data fields for names you can recognize the child und check the setting of the child number.
 
Now click on the right (Child [Part...]) on the Part... button. After a confirmation request the child will be parted.

This is not possible directly but look at the task from the other side: Instead of assigning a father to a child you can assign a child to a father with the same result. Read the topic How to assign to a saved person another saved person as a child?.

This is not possible directly but look at the task from the other side: Instead of assigning a mother to a child you can assign a child to a mother with the same result. Read the topic How to assign to a saved person another saved person as a child?.

Open the Personal Data dialog for the person and go to the Personal Data sub-tab.
 
If the person does not have any partnership and any child, you can change the gender in the area of gender without any restriction.
 
If the strict gender check has been selected in the Program Options, Integrity Check tab:
If the person has already a partnership or a child, you must click on the lock button for the activation of the radio buttons to be on the safe side before you can change the gender. Attention: If a partnership of the same gender arises from the changed gender, the next data integrity check will be reporting an error. In such a case also correct the gender of the other partner.
 
If the moderate gender check has been selected in the Program Options, Integrity Check tab:
If the person already has a child, you must click on the lock button for the activation of the radio buttons to be on the safe side before you can change the gender. Attention: If a partnership of the same gender arises from the changed gender, the next data integrity check will be reporting an error. In such a case also correct the gender of the other partner.
