Hi, yesterday I downloaded Parallels 8 (free Demo) and installed Win 8 consumer preview. In general it is running fine. But whenever Win 8 is running and I play videos under iPhoto/Aperture (latest updates loaded) I see a corrupted screen in Win 8 afterwards. Most times I can resolve this by clicking several times with my mouse in Win 8 but one even time my complete MacBook crashed / rebooted. I'm using MacBook Pro Retina 2,6 with 16GB memory, 768 SSD (4 GB and 4 of 8 cores assigned to Parallels). OS X is 10.7.4. Parallels should be the latest version since I downloaded it yesterday. Win 8 is the latest preview. Anybody experiencing the same issue? Any ideas? Thanks, Thomas
