FYI: If you have a form containing a subform datasheet, there are
instances where the main form seems to disappear and the subform is
the only thing showing. This doesn't happen in 2003, because the
height of the subform datasheet is somehow more rigidly defined. What
is happening is that the subform is receiving the focus (it may be
high up in your tab order). Set the focus explicitly to something at
the top of the form, or move the subform down the tab order. I haven't
found the best way to deal with this yet, post if you have better
insights.
