How do I do a smooth Pinch/Zoom ?

You didn't do anything that I suggested in my previous comment..

Start with my file zoom_sprite.capx, move blueBoxScale from global to instance variable. Save UID in some variable on first touch. On second touch don't check for "is touching sprite" (because the second finger may not be touching the box) and pick the box by saved UID instead.
