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
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.
