This morning, I upgraded Tiger to Leopard. I am running Parallels 3.0 Build 5160. When I started my Windows XP Pro VM, I discovered the following two issues: 1. On Tiger under Coherence, the Windows start menu was not displayed when my VM was in Coherence mode. After upgrading to Leopard, Coherence mode now displays the Start menu and the task bar along the bottom and there appears to be no way to turn this off. 2. I have my VM configured to mount virtual disks on the OS X desktop. After upgrading to Leopard, this auto-mount is no longer working. 3. During a shutdown/restart attempt of my VM, Windows displayed a pop-up window indicating that ParallelsToolsC was not responding. After clicking on End Program, Windows XP shutdown proceeded to the blue screen with the Windows XP logo stating "Windows is shutting down...". At this point, the shutdown hung. I tried to power off the VM but that causes Parallels to hang. At that point, I had to Force Quit Parallels.
