title: SCRIPT16389: Unspecified error -- Javascript code
body: <p>I'm getting a "SCRIPT16389: Unspecified error" for simply defining a small piece of Javascript.  This thing works in all browsers EXCEPT IE (yeah, freaking IE -- don't get me started).  I am testing this in IE10, but I was told that this is also happening in IE11.</p>
  
  <p>This is all I have in my code where it's failing (!!!):</p>
  
  <pre><code>&lt;script type="text/javascript"&gt;
      var isChild;
      if (window.opener == null) { isChild = false } else { isChild = true }
  &lt;/script&gt;
  </code></pre>
  
  <p>I've looked at other posts that have this same error.  None of them answers my question.</p>
  
  <p>Ideas, anyone?!?</p>
