That's a good idea, but unfortunately, that won't prevent
built-in IDL functions (like the aforementioned xplot3d) from
crashing the system. But I suppose if I let everyone who
is likely to use this system know, I can avoid this
eventuality.

Is that an anecdote from your personal experience David? :)

As it turns out, the object graphics programs I have
written do happen to draw lots of polygons. Maybe I'll check
the drivers first. I wonder if there ARE any
solaris 8 drivers for any good graphics cards.

Thanks for the input.
