title: AS3 ExternalInterface.call, why it doesn't work on Chrome or IE?
body: <pre><code>import flash.external.ExternalInterface;
  var pageURL:String = ExternalInterface.call('window.location.href.toString');
  </code></pre>
  
  <p>The above code seems to work on Firefox, but when I try it with Chrome or IE it doesn't work (it  causes an Error and stops the swf's execution).</p>
  
  <p>Any hint?</p>
