I wish I had a solution for your data entry problem with Generations software. I am using Generations 8.5, and have just begun, within the last week, having the same problem. The program is erasing the dates that I enter. I am also not able to enter both a surname and first name. When I hit enter, one of the names is erased. I have tried uninstalling and reinstalling the program, but this has not helped. If you find a solution to this program glitch, please let me know.
