That's really odd, since I don't.  (*grin*)  What I'm doing is using an HSV
color 3-tuple, since I only have to work with one element (the H, the first
in the 3-tuple) in order to get a full range of colors according to a
certain property of the object.  I then just translate the HSV to RGB for
VPython's use.  Even if the first element of the tuple were weird, the other
two elements are explicitly 1 and 1 (hue, 1,1).

Thank you, Jonathan, I'll try that, but I can't print anything to the shell
window; I'll have to try to write any messages to a file and even that
is unlikely to work.  When the program runs and expecially when this
happens, the program hogs focus and the CPU is in 100% usage.  I can't even
Windows-multitask at all and that's on a 2.2 GHz (Intel 3.4 GHz equivalent)
Athlon64 w/512 MB memory.
Thus I can't _see_ the shell without minimizing the stereo window, which
sometimes works (after a _long_ pause) and sometimes doesn't.  There's
no chance of catching "live" error messages, or more than one of them
if static.

This is all because the scene.exit=0 function (close the stereo window;
leave the shell and edit windows open) _doesn't work_ in this VPython (2.4).
I wanted especially to know if that has been fixed.
Has it?
(I know there's a new version up, but has this particular irritant been
fixed in it?  I can't go on forever re-initializing Idle every time I close
the stereo window.  It makes it really hard to work on a program when I have
to start from scratch every time I test some minor thing and have to close
the stereo window....)

Peace
