I was able to use RM4 on my Mac without problem by using Crossover. I've now installed RM5 and when I open my family tree, I'm unable to add facts for individuals. When I get to the Add Fact screen, it freezes when I try to select the type of fact (Military, etc.). I've tried restarting the computer and running these two programs without any others running the background (in case it was a memory issue). I have this problem with multiple people in the database, not just one. Any suggestions?
