Windows 7: Game won't shut down properly

[Metathron]

When I click the Exit button in the game, I am not returned to my desktop, I only get a black screen, and can't do anything at all, no alt-tab, no ctrl-alt-del. It's annoying as heck not to mention bad for the computer to have to use the reset button so often, any solutions?

EDIT: Setting the compatibility mode to WinXP SP2 and running the game as administrator doesn't help either.

EDIT 2: I thought I could shut the game down by alt-tabbing back to windows and shutting it down from there, but alt-tab doesn't work at all. So the game is esentially unplayable to me, unless I'm prepared to keep damaging my computer with violent shutdowns.
