title: Javascript hangs in IE unless in debug mode
body: <p>I'm building web a javascript application using jquery, knockoutjs and less (for css).</p>
  
  <p>Works fine in all browsers, except IE 9 (only tried IE 9).</p>
  
  <p>It simply never starts. Nothing from the templates are shown. Unless i press F12 for debug and refresh. Then everything works fine, also works if I close the debug window and refresh. Right until next IE restart.</p>
