Form is modal; displayed as: form.ShowDialog(this);

As I mentioned in my earlier msg, I'm hiding the form when you click a
button, not closing it. While dicking around some more, I found that if I
use the Form.Close() method instead, it eliminates the flashing. However,
that raises another point. Doesn't calling Close() destroy the form object
(or at least prepare it for garbage collection)?
