At work I have an external 20 inch display. I run my VM in full screen mode at 1600x1200. When I get home, I start up on my VM on my MBP display. THe VM is still at 1600x1200, and when I switch to full screen mode, Parallels crashes. If I lower the resoluition of the vm to 1024x768 and then switch to full screen mode, it doesn't crash. I haveboth "Animation mode" and "Change MAC OS X resolution" disabled. Michael
