I'm using motif widgets and I have a problem with the toggle button widget.
I use highlighting to show when the pointer enters the widget, and it works
for every widget (that I have checked) except for the toggle button widget.

Below, I have sample code that demonstrates the problem.  You can compile it
with something that looks like the following:

cc -o test test.c -lXm -lXt -lX11

Am I doing something wrong?  Do toggle buttons have a different behavior
than push buttons with relation to highlighting?  Is this a bug?

Thanx,
Chris
