Hm. That fixed it when I ws having the same problem.
Another potential problem arises if you have multiple IDL sessions running
at one time on the same console, especially if they are coming from different
hosts. I have no idea if that is your problem, however, but it is the only
suggestion I have left.

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).

Add this to your .Xdefaults file (or .Xdefaults.opn or whatever you call it):
Idl*colors: -5
This tells IDL when it starts up that it should not hog all of the colortable
(which is what it does by default), but leave 5 colors free. That way, when
you try and create a widget, there are still colors left in the colortable.
Please note that this change doesn't take effect until you logout and
log back on again :)

I suggest reading openwin3.doc in idl/notes directory. It has some recipes
for fixing some titsy bitsy yet annoying behaviors under Sun OpenWindows
similar to yours.
