I had been running version 18xx with no problems for may months. Just upgraded to 3036 yesterday, and now Parallels crashes about 9 out of every 10 times that I try to leave fullscreen mode. I am running XP Pro inside the VM. Some older threads suggested changing the hotkey to not include command or control; I tried that but it did not help. So the only way for me to get back to the Mac desktop is Command+H to hide Windows entirely.
