BTW, did I say that I hate that [cnv] gets confused with the other canvas object, and how it gets used for purely ?sthetical reasons? It should be called another name, like [dumb_rectangle], but it seems like it's too late.
ok... added a 'dumb' attribute...just select some rects and change dumb to 1, in the inspector: http://whats-your.name/pd/dumb.PNG
