I had started up Parallels and it gave me the message that there was an update available. I saw that it was to fix some 10.6.5 issues and some other items. As I was preparing my system to upgrade to 10.6.5 anyway, I downloaded the update and installed it. I then started my Win7 VM and Parallels promptly installed the new tools. And did the reboot. Reran my windows experience assessment and gaming graphics went from 3.9 to 4.2 but the basic graphics WENT FROM 4.9 TO 1.0!!!!!!!!!!!!! Obviously Aero got disabled. Reran the assessment and IT ONLY WENT TO 2.0!!!!! What is wrong with this picture??????? Note: 24" Imac 9.1 with 4 gig ram and 2.66 GHz C2D and nVidia GeForce 9400.
Update Completed updating Mac to 10.6.5 and reran my Win7 VM's assessment and now Graphics back to 4.8 and Gaming Graphics bumped to 4.3. From this I would say beware of updating to latest Parallels without updating to OSX 10.6.5.
