I haven't had this with previous versions but now I had LR 3 stopping my PC with Vista 64 Ultimate the third time!
I can only move the mouse but not use the task manager or anything else. After a while, I can only shut down the PC by switching it. Hours later after chkdsk und raid check (about 8 hours!) I can start again.
This problem alwas happens after working with LR 3 for about 2 hours.. PC is a dell quad core with matrix raid, 4GB Ram and nvidia 9500 GT.
What might be the solution?
