I've been using Motif 1.0's XmDrawingArea widget extensively for almost a
month and have not encountered the behavior you're seeing.  One thing you
might try is running the motifgif demo, which uses an XmDrawingArea widget,
in the demos/motifgif directory.  That demo works fine (and actually looks
very nice - look at the challenger.gif file on a color workstation) on our
machines (Sun3, SunOS 4.0.3).  So if you see the same problem on your machine,
then that might indicate a problem with how Motif and/or X11R3 was built on
your machine.  If you don't see the same problem, then that indicates a problem
with your code, such as somehow you're generating an expose event when handling
an expose event.
