I've read on more than one occasion that having better graphics support is planned, probably emulating a reasonably modern and capable video card, like the SiS 6326 (IIRC). If you have some knowledge in that area and is willing to help, you're more than welcome :) cheers, -- "A year spent in artificial intelligence is enough to make one believe in God" Alan J.
