title: selectNode() not working in IE8
body: <p>I need to select a node in tiny mce, I'm trying following code. It works in non-IE browsers, but on IE it gives error as - 
     <strong>Error: Object doesn't support this property or method</strong> </p>
  
  <p>Code - </p>
  
  <pre><code>              rng = ed.selection.getRng();
                rng.selectNode(tn);
  </code></pre>
  
  <p>The second line causes the error. Is there any other IE compatible method for this ?</p>
