Drag and Drop (simple)

Question

Hi guys
I'm trying to make a simple drag and drop game.  I've named the movie   clip in the properties window as "eye" and have written the following   code in the frame.
I can pick up the movie clip, but not put it down.  Can someone please help me?
I've attached the file: http://www.flashadvisor.com/forum/attachment.php?attachmentid=255&d=1285202999
Any help you can give to help me solve this will be much appreciated by me and a couple of hundred students i teach
Thanks

eye.addEventListener(MouseEvent.MOUSE_DOWN, pick_up);
eye.addEventListener(MouseEvent.MOUSE_UP, put_down);
function pick_up(event:MouseEvent): void {
trace("pick up ");
event.target.startDrag(true);
function put_down (event:MouseEvent): void {
trace("downdowndowndown");
event.target.stopDrag();
eye.buttonMode = true;

Answer 1

MOUSE_UP event listener should be added to stage - not the object:
eye.buttonMode = true;
eye.addEventListener(MouseEvent.MOUSE_DOWN, pick_up);
function pick_up(event:MouseEvent): void {
     trace("pick up ");
     event.target.startDrag(true);
     stage.addEventListener(MouseEvent.MOUSE_UP, put_down);
function put_down (event:MouseEvent): void {
     trace("downdowndowndown");
     stopDrag();
     stage.removeEventListener(MouseEvent.MOUSE_UP, put_down);
