Yesterday I installed Parallels 5.0.9220.531073 under OSX 10.6.2. All has gone well except that three times, the machine has been seized by an unstoppable flipping back between 2 apps in Windows XP2 (e.g. Firefox/Windows Explorer or Firefox/Eudora). It stays in each one for a fraction of a second, then flashes over to the other. The only way I can stop it is by exiting Crystal, then re-entering. I can't identify any triggering action on my part. Ideas?
I don't have any ideas, but I have the same problem running Outlook and another application in Vista. Rapid cycling between two applications and no easy way to stop the problem.
