Parallels 4, Vista guest, black screen

**I rebuilt my VM from scratch and I did not have the same trouble, please don't feel obligated to help me troubleshoot this. Old VM has been deleted. Thanks

Hi, This is a non critical guest os, but I did spend a lot of time configuring it

Basically the problem is that the Vista guest OS blackscreens after boot. I know it is running because the vista screensaver will kick in, but when screensaver is interupted it just goes black with cursor.

This is a new installation in Parallels 4, not a migration from 3.

Installed are: SP1, MS Office, Kapersky, CutePDF, Foxit, and Firefox.

Last successful boot I ran Parallels Compressor, I did not see it give an error.

Thanks,
SeqTeq
