I have Generations 184.108.40.206 on XP home edition. It worked great with Win98 and ME, but on XP, 50-50. The problems I have is relationship listing may sometimes cause it to freeze up, and also when entering data from one field to another on a persons card, the previous data field will go blank. I still like it over FTM however. I think it is more user friendly, so I put up with the occasional gliche.
