I need to catch an event when mouse leaves the flash player window. This:

```auto
stage.addEventListener(MouseEvent.MOUSE_OUT,leaves);

```

doesn’t work properly if the stage is not filled with childs! And more, I can’t understand that: did mouse leave stage or a child of stage??

Please help! :diss:
