title: Mootools menu does not work in IE9
body: <p>I am using this mootools menu in a project. It runs perfect in all the browsers but IE-9 does not load the JavaScript. Please help me on this.</p>
  
  <p>The Mootools code is given below for reference.</p>
  
  <p>The menu is taken from <a href="http://greengeckodesign.com/menumatic" rel="nofollow">Here</a>
  I have used the menu in <a href="http://www.natoria.co.uk" rel="nofollow">This Project</a></p>
