title: GWT Hangs at startup of the application before onModuleLoad
body: <p>We have GWT/GXT 3 application (mostly migrated from gxt 2 but still has a few little areas that are not updated yet). The application will hang at its loading screen (just a div with a spinning gif) and not complete, this however only happens on IE8 for just one of our clients.</p>
  
  <p>It does not reach onModuleLoad to start the app and appear to hang during downloading of the javascript. <strong>Is there any more I can do to debug this?</strong></p>
  
  <p><strong>Little More Information</strong></p>

  <p><strong>Edit</strong>
  Added to mention this is a live system which works for all other clients and is only an intermittent problem for the client in question</p>
