Hello,

I am trying to catch the FullScreenEvent when the user enters or exits full-screen mode.  
In the following code, I just wanted to see that the event is handled, but unfortunately no event is received when I enter full-screen mode from the flash player.

```auto

stage.addEventListener(FullScreenEvent.FULL_SCREEN, FullScreenHandler);

protected function FullScreenHandler(fsEvent:FullScreenEvent):void
{
            var s:Sprite = new Sprite(); 
            s.graphics.beginFill(0xffffff,1);
            s.graphics.drawRect(10,10,30,30);
            s.graphics.endFill();

            if (stage.displayState == StageDisplayState.FULL_SCREEN)
            {
                addChild(s);
            }
            else if (stage.displayState == StageDisplayState.NORMAL)
            {
                removeChild(s);
            }
}

```

Am I doing something wrong, or maybe the FullScreenEvent is never sent when toggling full-screen mode from a flash player?

Thanks,  
OML
