I've got the GLJPanel samples working on 98, NT, and 2000 (all laptops with
varying quality video cards). I had to pull down the number of colors on
the display down to 256 colors on some of them (not sure how strong the
video cards are). I assume this is the issue? Anyway, when the numColors is
too high, the error is very cryptic. Line 234(?) fails with the "setpixel
failed" message. A better message would be in order, I suppose. I'm kind of
new at this, I don't see why this order of calls should EVER fail (these
are in SetDCPixelFormat):
ChoosePixelFormat
SetPixelFormat
but it does!
So if you get the "setpixel failed" message, try reducing the number of
colors and the samples will work.

Thanks for the clear bug report. This patch should fix the
problem. Will be checked in to the cvs tree shortly.
