if you can write a modal dialog loop, you should make the effort to go the
next step and write a modeless dialog loop which emulates a modal dialog
as much as you'd like.  the benefit of being modeless is that you can
then handle null events (and you must handle others, like update and
activate events).

modal dialogs are nice for _simple_ things ...
