I am trying to subclass a toggle button widget to create a 3-state button 
which has true and false states as well as a third neutral state.  So far
I have not had much luck.  I have experienced crashes that seem to relate
translation management and right now things seem to hang after the 
application calls XtMainLoop.

Has anyone had experience subclassing the toggle button widget?  Or has
anyone written a 3-state button widget?
