Is there any specific type of instability indicated when Logic 8 usually crashes on Quit? I always have to Force Quit to get it to quit all the way. It always wants to send a report to Apple, but I'm sure they're tired of hearing it by now. This is happening with Lion but did the same thing with SL. Repairing permissions seems to help sometimes, but it's only good for maybe one session. Any ideas? Anything I can try that might improve my stability?
