title: TinyMce editor text box not editable
body: <p>I have a strange problem with the TinyMCE editor on one of our pages. 
  The control renders fine but the user is unable to type anything into the text box. And no, it is not locked.
  If the user logs on to the same page from another computer then it works! It has something to do with the browser on his machine (IE6/IE8). The page works fine on Firefox on the same machine.</p>
  
  <p>The user initially had IE6 when the problem was reported. The browser was upgraded to IE8, but the problem did not go away.</p>
  
  <p>Anyone has a clue?</p>
