I previous of flash there was no way to detect when the users mouse had left the flash movie.

Actionscript 3 now allows you to detect when the users mouse has left the movie using the mouseLeave event.

Lets take a look:

package {
    import flash.events.Event;
    import flash.events.MouseEvent;

    public class mouseLeaveTest extends Sprite {

        public function mouseLeaveTest() {
            stage.addEventListener(Event.MOUSE_LEAVE, mouseHasLeft);
        }

        public function mouseHasLeft)(e:Event):void {
            trace('Mouse have left the stage');
        }

    }
}
