I'm writing a program that displays digitized color images using
X11R3, Xt, and Athena widgets.  It was working fine using SUN O/S 3.5.
We just upgraded to O/S 4.0.1 and now when I run my code
the core widgets that hold each image appear on the screen, but
they're blank!  When I run the code using the Saber-C debugger, it
runs fine, except for the blank images.  When I don't use the
debugger, the program is bombing in what appears to be random places
involved with the image creation, usually at XPutImage.  

I don't think I changed anything relevant in my code, but at this
point I may be losing my mind...  Any ideas?
