I forgot to mention that they APPEAR in the correct coordinate locations on
the form, but when they refresh (via clicking or via updating the
scrollbar) - the system redraws them in the offset positions.
any help from anyone would be greatly appreciated for this. I really don't
like using a full-screen form for what I'm doing, but I have no choice..
thanks - bill
