The X toolkit only processes events in XtMainLoop.  Even though you have asked
the label widget to display a new string the event is not sent to the server
until you get into XtMainLoop.   A quick fix to the problem is to put an
XFlush() call into your client after the XtSetValues() call.  This will flush
the request to the server immediately.  If you do not have backing store active
then you may run into problems if your label is obscured, when using this
method.  

NOTE:  This method assumes that your label widget is mapped and viewable before
       you enter the callback proc.  If you want to pop up the message label
       then things get more complicated.
