Crash on Lion, when trying to exit full screen mode

Hi,
I can’t work anymore with Scrivener. The app just crash when trying to exit Full screen mode. I have read somewhere here that Airfoil was the culprit. I don’t have that. Do you have other clues about this problem?
Thanks in advance.

Removing ui.plist seems to have solved the problem. Unless it was something else, but who knows. It is a little bit frightening when you’re finishing a novel…

Do you mean Lion’s full screen mode (not composition mode)? Could you please post the crash log? No one else has reported anything like this so I’m afraid there’s not much to go on without seeing the crash log.
Thanks,
Keith
