GrabImage problem

When I run this code:

in window mode with the dx drive it works fine.
when I run it with the glmax2ddriver it works fine windowed or full.
But when I run it in in full screen mode with the dx driver, it doesn't display anything. Does anyone else have this same problem? I am thinking it's my graphics card or driver.
???
it could also be a GrabImage dx problem.

try it on another graphics card if possible. I believe there are some documented issued with the dx driver this may be one of them.

If you know gl works is there a specific reason to stick with dx? Personally I prefer gl, but I always develop cross platform so I'm more than biased...

thanks for testing. I found out it was a driver problem. the driver was from the manufacturer Inno3d. I downloaded the one from Nvidia and it worked fine now. The only problem now is that some of the options are no longer there. Not that I needed them anyway.
