I think you can resolve the size problem in a general way.  Once you've
built each of the overlaid widgets (with map=0), call
Widget_Info( widget_base, /geometry) for each widget.  Determine the
largest xsize and ysize and then use Widget_Control on each widget to
set its xsize and ysize to the largest value.  I happened to try this
just yesterday for a similar problem and it seems to be working okay
(at least so far ;-).
