   I have noticed a problem updating the values of several widgets
(mostly labels) during one of my callback routines.  The 
callback routine is a computationally intensive routine, where through
the first iteration of the loop it calls XtSetValue() on various
widgets to update their values.  I am noticing that these labels go blank
and are not updated until the "Big loop" is finished.  I understand
why this is happening (I think) but I thought if I put 
XFlush(XtDisplay(toplevel)) after the widget values are changed 
the events would be handled.  But this is not the case.  
Must I dispatch events during this "Big loop" to guarantee updates?
Any input that sheds light on this subject would be appreciated!!  

			Thanks.
