I have the current version of FTM Mac 2. Tonight my file on my computer unlinked all children from their parents, sort of. If you go to a child, you will see the parents, but when you click on the parents, no children appear in the screen below even though the child still appears on the main screen pedigree chart.
I have used Family Tree Maker off and on for several years in both Windows and Mac and have always had various problems with the program corrupting files but this is a new one.
I'm very disappointed to see how horrible Family Tree Maker support still is after all these years and wish there were an alternative.
