No need to redraw() - setting Visible = True (note: 'true' is not the
same as 'True'!) will redraw the button if necessary. And unless you
set Visible=False initially, it should default to True.

Is this code being run in the Hit event of the button? Or is it being
run from somewhere else? Also, are your buttons on the form, or are
they on something like a toolbar?
