title: Prevent exit fullscreen when "ESC" is pressed in Flex
body: <p>We have a Flex application which goes fullscreen on startup (which is possible when it's a projector .exe). When a user presses ESC, the application exits fullscreen mode. Is there any way to prevent this? This because we want to use the ESC-key for other functionality.</p>
  
  <p>Normally all keyboard input is disabled in fullscreen mode, but not when we run it as a projector. </p>
  
  <p>I already tried capturing the <code>FullScreenEvent.FULL_SCREEN</code> event without luck (this event is only fired when the user selects "Full Screen" in the Adobe Flash Player or hits "CTRL + F".</p>
