I am running Parallels Build 6.0.11994 with XP SP3 on an iMac 21.5-inch: 3.06GHz using OS 10.6.7. For some reason my Apple Magic Mouse causes some proprietary database applications to quit unexpectedly. When I connect ANY other Apple or non-Apple Bluetooth mouse the applications respond perfectly. Likewise if I use any Apple or non-Apple USB mouse the applications respond perfectly. I have narrowed the issue down to the Apple Magic Mouse. Has anyone else experienced anything similar?
