BackBuffer creation fails.

Hello all,
I have an ATI video card and using Microsoft generic driver, the problem is that as I open more windows in my MDI app, a black strip appears (bottom and right) and nothing gets drawn in those strips. I switch my app to use only one buffer, and it does not happen, So I guess it is a problem with the buffer size…is there a way of checking/handling the backbuffer creation/size?..would it be posible to force it to be in the Pc’s ram rather than in the onboard ram?..Please any comments/hints will be really apreciated.
Thanks,
Asdiel.

If an OpenGL driver runs out of video memory, it is required to fall back to system memory and software rendering. So this would be a driver issue, though I’m surprised that you’ve seen it with the MS OpenGL driver, because I would doubt that they would handle this wrong (MS OpenGL always uses SW rendering).
