There is one little trick you can use to help set up the Custom Tags initially. It relies on the fact that when you copy an object from one GenoPro file to another GenoPro also brings accross any Custom Tag definitions and Custom Tag Dialogs. To make use of this I have created a GenoPro file with the Custom Tag definitions it and a single Label in the only Genomap. If you open this file and copy and paste the label into your target GenoPro file it will drag the Custom Tags definitions across too. You can then immediately delete the Label from your target file, leaving the Tags in place. Note that this only works for the definitions of the Tags, not instances of the Tags so no initial default values are set. Note also if the Tag definitions and/or Dialogs already exist in your target file then they are not overwritten, so for example tag descriptions are not changed and any existing Dialog Layouts remain. I have attached an Xml version of the file if anyone wants to try it. As far as I know nothing else in your target file will change.
Be aware that once the tag definitions are in your file the only I know to remove them is to edit the Xml. Instances of the Custom Tags are removed when they are set to blank.
The installation of the Custom Tags required to do this is (I believe) not documented, and I recall it taking about an hour to do and then another hour of testing to ensure there were no errors.
Could these tags be installed permanently in the program , so that all users can access them and avoid having to edit the Config file.
