     The scenario is similar: a form with three command widgets, all 150 pixels
     wide (random strings as labels).  After you create these widgets, toggle
     the XtNsensitive attribute on one of the widgets.  For some reason, the
     form seems to think that the widget needs resizing and it shrink's the
     width to the minimum according to the string.
     
Slightly different issue here.  It's not the Form that's causing the
problem but rather the Command (Label) itself.  By default, every time
you do a SetValues on a Command (Label), it will make a geometry request
to be resized to it's optimal dimensions.  There are two ways to
disable this: the XtNresize resource in Command (Label), or the
XtNresizable constraint resource in Form.  The former is documented,
the latter is mentioned but not well documented.  Since the default
value for the latter is to disallow geometry requests from the child,
you must have already discovered it.
