Hi Calico,
It would really help if you can give me some steps to reproduce the problem. Crashing like that is not normal behaviour. Somehow you are doing something that is causing the crash. If I can understand what that might be I can look into solving the problem. As you might imagine I've done a fair bit of testing of the animation panel on both the Mac and Windows and I don't have these problems, so just knowing that it crashes doesn't really get me very far. If you can give some steps to follow which always cause the problem for you then that would be a massive help. Another alternative might be to make a screen recording if you have any way to do that, so I can see what you're doing.
Regards,
Jo
