I described an IDL crash following the message
OPEN LOOK Toolkit Error in application "idl": Can't allocate gray pixel

I already have that.

Unless you do 'xrdb -merge .xdefaults' :-)

This document also suggests the Idl*colors business.

I thank Messieurs Offenberg and Hatay for their suggestions. I have changed
Idl*colors to -10 for now, which will hopefully reduce crashes due to color
table problems. I am more concerned about the mysterious segmentation faults
and bus errors which occur now and then. Unfortunately, I can't reproduce
these crashes at will. I can't even be sure my own machine isn't at fault.
Sometimes I have IDL sessions going for days, with many variables added and
deleted, which may complicate memory management issues. Also, I am not using
OpenWindows directly--I'm using twm with X11R5 (and IDL 3.0.0).
