Really? Then you have newer source Cello than I do ... ;-) Must have been something you did after the last CVS push ... I can't find any mouse-over? in any Cello or Celtk code over here. I am digging deeper ...

Do you have a mouse-view slot being maintained reliably? The observer on that setfs the mouse-over? (or mouse-over-p) slot of the current view, which should of course be c-input.

Yes, I had - but only after adding class 'cello::mouse-view-tracker to the superclasses of my Cello Widget base classe 'GNC-WIDGET ... and the following change to file ix-togl.lisp:

(defobserver mouse-view () (when old-value (with-integrity (:change 'mview-lost) (trc "mouseover lost by" old-value (window-cache old-value)) (setf (mouse-over-p old-value) nil))) (when new-value (with-integrity (:change 'mview-gained) (trc "mouseover gained by" new-value (window-cache new-value)) (setf (mouse-over-p new-value) t))) .retog.) ;; <<<<<<<<<<< - Added .retog. to trigger display update - needed to reflect mouse-over-p change

...

Thx again for pointing me in the right direction, Kenny!
