Um, this doesn't work, does it?  At least it didn't when I tried it.  LClick
tracks the mouse until mouse up, but so does the Dialog Manager when
resolving a mouse click.  That means that after ModalDialog returns an
indication that the mouse was down in the list user item, it's already too
late for LClick, the mouse is up.

What I had to do was put the call to LClick in my filter procedure.  That
works fine.

This is of more than theoretical interest to me.  I currently have a 'cdev'
(Control Panel file) into which I would really like to put a list.
Unfortunately, the Control Panel does not hand you mouse events in time to
pass them to LClick.  Most other events do get passed to the cdev code
resource, so this is fairly annoying.  Does anyone have a solution, short of
silliness like trap patching?
