title: Why window.opener not working in Internet explore 9?
body: <p>I have a JSP file which contains the following javascript</p>
  
  <pre><code>&lt;script type="text/javascript" language="javascript"&gt;
      window.opener.myfunction();
      window.close();
  &lt;/script&gt;
  </code></pre>
  
  <p>This works file on Chrome, Firefox. It also works on my Internet Explorer 8 and 9 which runs in VMWare virtual machine. However, a user reports a bug which turns out to be that the window.opener does not work and myfunction is not called. The user uses IE9 as well but running on a native windows machine.</p>
  
  <p>My question is that why it works on my IE9 but not his? Could any of the IE settings causes this? </p>
  
  <p>Many thanks</p>
