Aero Glass mysteriously disappears

Question

I am running Windows 7 in a VM (Parallels 5 on Snow Leopard). Every once in a while it decides, all on its own, that I really don't need the Aero Glass UI and turns it off. Rebooting the VM restores it.

Has anyone else seen this behavior? Is there a way to fix it?

Answer 1

Lots of other people have seen this behavior. A fix will be rolled out in the next Parallels Desktop 5 update as confirmed by a Parallels Team member (see here).
