Is it all the DirectX components that do this?  Or is it just limited
to the likes of Direct3D?

I am curious, has an OpenGL implementations be known to do anything similiar?

I have been using OpenGL since the mid nineties and haven't a problem
like this yet, but then I still mainly work under unices of various
flavours.  I do have quite a few users of my software  under Windows
and haven't heard reports of problems yet, but it sure be nice to know
if the OpenGL driver does it to so I can plan hacks around...

Cheers,
