Have you tried shadowing WINDOW-SELECT?

	(defobject *unselectable-window* *window*)
	(defobfun (window-select *unselectable-window*) ()
	  )

You could also have your WINDOW-SELECT set a global variable to record
which window was clicked on.  That will let you keep track of which
window the user pointed at (relating to your first question, not quoted
above.)

However, I think you're trying to solve the wrong problem.  There's a
window variable called WINDOW-DO-FIRST-CLICK.  It eliminates the
confusion of having your first click "eaten" by window select.  I always
set this to be true for any non-document-type window classes.

Not to pick on Kevin, but: The MACL interface to the window system is
full-featured (more or less) and quite flexible.  IMHO, with one or two
exceptions, if you find yourself calling traps directly in your
interface code, you're probably doing something wrong.
