Joe,I found that by upgrading the BIOS on my system I was able to access a new feature in the BIOS which allowed my to use 8MB of video RAM vs. the standard 1MB of RAM on earlier versions of the BIOS. Solved the problem immediately. I was using BIOS version A02 on a Dell Optiplex, and am now using version A06.
Hope this helps, b -- Bren Smith
