Thanks..... looks like this is window relative not screen absolute.  

Pretty it sure it won't work with setting the tooltip but hope to be proven wrong :)

I'll test it later tonight.

Here is what I have. There is indeed a problem with the left margin.
What change do you propose?

(defun point-to-coord (point)
 "Return coordinates of POINT in selected window.
The coordinates are in the form \(\(XOFFSET YOFFSET) WINDOW).
This form is suitable for `popup-menu'."
 ;; Fix-me: showtip.el adds (window-inside-pixel-edges
 ;; (selected-window)). Why?
 (let* ((pn (posn-at-point point))
        (x-y (posn-x-y pn))
        (x (car x-y))
        (y (cdr x-y))
        (pos (list (list x (+ y 20)) (selected-window))))
