I'm trying to verify the conditions under which all the various DIALOG
events occur, so I've been running experiments.  So far, I have been
unable to produce the following kinds of events, regardless of what I
do.  I wonder if any of you out there could show some sample code that
produces any or all of the following:

_efClear (event = 11).
_cursEvent (event = 20) with any non-zero id.
_preview (event = 22) with id = _wndDocWillMove (id = 9).

Thanks.
