There's no setting enabled to allow you to do it. At least not in Access
2000.
It might be possible (i.e. I haven't tried) to do it via code by using
something like the resize event - but that only affects the size of the
window, and not of the form - so the obvious solution of just using me.width
won't work. So you'd need to be getting into APIs to grab the size of the
window, possibly resetting the size of the form, and then resetting the
position of the control.
Which sounds like a lot of work.... so I think I'll stick with the original
answer and just say 'No'.
