Is this patch correct to test d3d7 and d3d2 SetCooperativeLevel? For now, all the tests pass on a real vista box.
Actually, I missed something: The exising test tests IDirectDraw, not IDirectDraw7. So it is testing the oldest ddraw interface. Can you test IDirectDraw7 instead of IDirectDraw2? If microsoft added extra sanity checks they did so most likely in the newer interfaces.
