title: IE9 JavaScript error: SCRIPT5007: Unable to get value of the property 'ui': object is null or undefined
body: <p>My website works well on Chrome, Firefox, and Internet Explorer 8. But on Internet Explorer 9, very weird errors are triggered when just hovering over components.</p>

  <p>And following the link to the error in the javascript shows me these bits of code:</p>
  
  <pre><code>onNodeOver:function(B,A){A.ui.onOver(B)},onNodeOut:function(B,A){A.ui.onOut(B)}
  </code></pre>
  
  <p>I'm a little clueless on how to go about solving this error. 
  I've seen <a href="http://forums.asp.net/t/1672835.aspx/1?CollapsiblePanel%20not%20working%20on%20hosted%20server">this</a> solution but that didn't solve the problem for me.</p>
  
  <p>Any Ideas?</p>
