EDIT: This has been solved using texture mapped quads instead of glDrawPixels

Hi, I'm not sure if this is the correct forum to be posting in, but I've been doing some openGL development, and I'm having a problem with fragment shaders on the ATI Radeon 3450HD. It seems as though the fragment shader is not applied when glDrawPixels is used to draw a set of pixels, but this works just fine on nvidia cards (and some newer ATI/AMD cards). The drivers are up to date (we have the latest from the dell site, which are from 2010, though not the latest from the AMD site).

Has anyone had experience with this before?

Thanks,
Jeff
