	An application I'm working on has a List widget within a
Viewport widget (both from the Athena set).  What I'm being given
headaches over is making the Viewport scroll so that a certain part of
the List is shown.  I'm having no trouble doing with this manually
with the scrollbar, but I haven't been able to do it automagically.

	What Viewport.c seems to do when the Scrollbar tells it that
it's supposed to scroll is move the ListWidget.  I haven't had any
luck doing this with XtGeometryRequest.
 
	thanks in advance...rj
