come non detto risolto il problema (comincio a gestirmela decentemente)...allego sorgente...
in pratica ho aggiunto un
preview_mc.addEventListener(Event.ENTER_FRAME,draw Rectangle);
subito dopo il CreatePreview ed in tale funzione aggiungo un offset per spostare il rettangolino
preview_mc.x=offset_posx+thumb_mc.x;
preview_mc.y=offset_posy+thumb_mc.y;
avendo prima dichiarato la posizione su cui voglio spostarmi
private var offset_posx:Number=110;
private var offset_posy:Number=70;
...e come d'incanto all'avvio dell'animazione si sposta rettangolino e immagine zoommata...
Ciao
