;;; I've been having some trouble with screen redraws following
;;; garbage collection. Below is some code that has similar
;;; behavior to what I'm encountering.
;;; Invoking redraw-all-everytime redraws the entire screen.
;;; It looks as if _InvalRect is called using the screen rect.
;;; This looks particularly klunky when there are several images
;;; on a screen.. everything disappears and then pops back as
;;; the view-draw-contents methods are invoked.
;;; So... is there any way of preventing a global redraw?
