I have a menu bar cascade button that invokes a somewhat lengthy
graphics re-paint.  The problem is that the menu bar being "modal" locks
out or "redirects" all other window input until the the processing in
the button callback is complete.  Thus while my graphics is painting,
the whole server is useless.

What is the best method to circumvent this problem?  I tried to use
XtRemoveGrab, but I could not find a "widget" to use it on.  I could put
the repaint in a different (user) callback, but how do I get motif to
execute a user-generated callback?
