Or install virtue desktop and run Parallels on a different desktop. I get the same error occasionally and my usual cmd-tab doesn't switch to Parallels. But since I run it on a different desktop I just click the menu and select my "windows" desktop and I'm back in Parallels.
I use a MacBook Pro with a USB mouse. I get the error when I close the lid (sleep) and go to a meeting, then return to my desk, plug in the mouse again and open the lid. Then I try the cmd-tab to Parallels and get the error you noted. It's very repeatable, but apparently doesn't mean anything because just switching deskops gets me back in.
