Rick, FYI, the NVidia antialiasing worked just as you suggested.
I liked the Quincunx method the best for my plots, better than the
methods available on the Radeon. Am now using Windows XP.

However, I found my Radeon computer 5-10 times faster than my
NVidia computer! At a wild guess I suppose that Nvidia OpenGL
"extensions" don't help IDL much. It may be a hardware difference,
but you wouldn't guess it looking at the two systems:
1) Nvidia G3 Ti200, dual Athlon MP1800, ASUS motherboard
and
2) Radeon 8500, single 2GHz Pentium 4, ASUS motherboard.

Both of these cards are appalling on their respective linux partitions.
Radeon 8500 is completely unsupported (ie software rendering)
and the linux NVidia driver somehow won't do direct rendering
for me.

Later in the week I'll send a detailed post for the edification
of the list.
