[AG-TECH] Greyed Vic Windows

Just wanted to follow up for the AG-Tech archives.

Turns out the person was using an "Velocity 128 made by STB" video card which used NVIDIA
drivers....  not one of the higher end video cards ;-)

He ended up installing on a different computer and all is fine - so the problem was never actually
solved, but I assume it was a video card/driver issue.

Thanks for all your help/input.
