Status changed to 'Confirmed' because the bug affects multiple users.

It worked great for about 2 minutes. When I tried to open the fusion menu compiz crashed, attempted to restart and the system froze. I have the latest kernel. I will try to provide you all of the information about the crash as soon as possible. Quite busy at this time.
