Since I first posted this article, I've been kicking myself for not detailing
my X environment.  Sorry.  I am using X11R4 patch level 18.  The only resources
of relevance to the program (stored in the resource property on the server)
were:-

*borderColor:			white
*background:			black

It turns out that removing these resources makes the problem go away.
It also turns out that the problem can be demonstrated without creating
or realizing any widgets!  Here is a simpler version of the original program
which exhibits the same behaviour:-
