Close the browser window by fl button

programming flash
1

Hello everyone !

I have my game in a browser window (incredible !).

I put a red cross in top of my game and want that it close the window.

I’m using the following code :


close_btn.addEventListener(MouseEvent.CLICK,close_window);

function close_window(evt:MouseEvent)
{
    ExternalInterface.call("window.close()");
}

and the js console answer :
Scripts may not close windows that were not opened by script.

any trick ?
thank you !
