Does anyone have a trick for locking Parallels in full screen XP mode? There are situations when I am giving demonstrations to very large audiences. Although it is cool to see the 3-D swivel from full screen to the Mac OS it can be very bad and embarrassing if it happens accidentally. I've remapped my Ctrl/Option full screen key to something more obscure but things like CTRL-Tab to toggle Mac applications still get me now and again. Any clever workaround would be fantastic, thanks.
