OK; sorry about the delay -- I needed to use the machinie for a while (at work), and then I had a weekly staff meeting.... Anyway... I've attached results of the above. For the first & last, I did each twice -- once using the "nv" driver, and once using the "nvidia" driver. (The middle one only got the "nv" driver.) So the files are: kib_0_nv kib_0_nvidia kib_1_nv kib_2_nv kib_2_nvidia Peace, david --=20 David H. Wolfskill david@catwhisker.org Taliban: Evil men with guns afraid of truth from a 14-year old girl.
