platinumgodMight be talking out of my arse here but I think -nod3d9ex1 may help? I've heard a lot of talk about it. Note the distinction between -nod3d9ex1 and -nod3d9ex (the one that apparently helps).
so now I can ctrl-alt-delete as a form of tabbing out, but not alt tab
windows button also works, though opening task manager wityh ctrl shift esc blackscreens it too
