title: Flash - Mouse Event Handling (Make symbol transparent to mouse)
body: <p>I have a flash that has a background symbol that responds to CLICK event.
  On top of that symbol I have a sprite that contains a Bitmap with transparent pixels.
  Both of them are added to the stage, so they are not related directly.</p>
  
  <p>I want clicks on the transparent pixels on the sprite to go straight through to the background.</p>
  
  <p>I have read about mouseEnabled / mouseChildren but have not been able to make these work.
  The symbol ignores the mouse events when I use them, but does not pass it along as if its transparent.</p>
  
  <p>Is this possible to do with flash? Or will I have to re-route mouse events?</p>
  
  <p>Thanks</p>
