Home Forums Networks & Cross-Platform Other OSes on the Mac Parallels Flashing in Windoze 7 Pro

I'm on a MBP 2.0 Quad-core i7, 8 GB RAM, running Lion 10.7.3.

I've got a Windows Partition, running Windows 7 Professional with Parallels 4. I'm only running one program on it, which is Java-based, a beverage ordering program that runs on Java, VIP. The latest Java updates have been applied.

There are many times, all at random, when my Parallels screen starts flashing and pixelating. I've been looking on the Parallels Forums and am not finding much so far. I have found some posts about Paralles and Unbuntu running into a somewhat similar problem, but doesn't seem to apply here.

The only way it stops is to suspend the Virtual Machine, and even then, it comes back sometimes. I've run a virus/malware sweep, can't seem to find anything, wondering if anyone has any ideas.

The Windows Partition is only 50 GB, but I've got over 1/2 the space free. I don't really store any files in Windows, I just use it for the beverage program (VIP).

Thanks,

Chris K

Sounds like a video driver problem. Either the parallels video driver isn't installed correctly or the video settings in Parallels aren't right, or there's a weird interaction between Parallels and your Mac's real video card.

Reinstalled Parallels tools, so far so good...

Thanks Tacit as always!
