title: Tridion Powertools Script Errors (2009)
body: <p>Installed the Powertools on a dev '09 system - now I get the script error "Unable to set the value of property 'async' : object is null or undefined"</p>
  
  <p>I'm thinking this is possibly because I'm using IE9 in compat mode which I don't believe is supported?</p>
  
  <p>Thanks</p>
