When the mouse button is released, the morph is dropped from the hand to the underneath morph (which may accept it or not). I am looking for a slightly different behavior, instead of grabbing by the hand->moving->dropping from the hand (with the change of owner), I want dragging the morph within its owner, the morph owner does not change. Therefore the morph will never move out of its owner, being dragged over other morph. Is it possible to do so without adding a specific behavior to the morph, but instead adapt the owner morph? hilaire <pre class="moz-signature" cols="72">-- <a class="moz-txt-link-freetext" href="http://mamot.fr/@drgeo">http://mamot.fr/@drgeo</a></pre> </body> </html>
