When I'm in presentation mode in PowerPoint 2008, and I deliberately or accidentally switch to another app, PowerPoint forces my dual monitors into mirrored mode.
Apart from shrinking my desktop and repositioning many dozens of windows, this also forces fullscreen virtual machines onto my main monitor, such that I can't get at the menu bar without unzooming them (and consequently messing up their desktops).
Does anyone know how I can prevent PowerPoint from doing this? Does PowerPoint 2011 do the same thing? (And does it introduce yet another incompatible UI?)
