Disable ESC in Fullscreen in AIR application

Question

Hi,
I would like to remove default air behaviour that it's resizing down after hitting ESC button. I red that this is possible with 'preventDefault();' method, but it seems not to work. My code below:
private function init():void {
     stage.displayState = StageDisplayState.FULL_SCREEN_INTERACTIVE;
     stage.addEventListener(KeyboardEvent.KEY_DOWN, ifEsc);
private function ifEsc(e:KeyboardEvent):void {
   if (e.keyCode == Keyboard.ESCAPE) {
   e.preventDefault();
Anyone had simmilar problems?

Answer 1

      public function eend(e:Event):void{
        e.preventDefault();
        e.stopPropagation();
        e.stopImmediatePropagation();
private var winDisplayStateTimer:Timer;/// put lines below in some initializer
      winDisplayStateTimer=new Timer(0);
      winDisplayStateTimer.delay=2000;
      winDisplayStateTimer.addEventListener(TimerEvent.TIMER,onWinDisplayStateTimerTick);
      winDisplayStateTimer.start();
/////////////////////////////////////////       private function onWinDisplayStateTimerTick(evt:TimerEvent):void{
         if (stage.displayState != StageDisplayState.FULL_SCREEN_INTERACTIVE) {
           stage.displayState = StageDisplayState.FULL_SCREEN_INTERACTIVE;
