title: CSS Disabled scrolling
body: <p>I came across an issue with one of our web sites: </p>
  
  <p>In IE9 the page had a vertical scrollbar, but you couldn't use the mousewheel, arrow keys, pgup/pgdwn to scroll.  The only way to scroll was to actually click/hold and move the scrollbar.  </p>
  
  <p>I removed the following from the css:</p>
  
  <pre><code>{
      overflow-x: hidden;
  }
  </code></pre>
  
  <p>Then scrolling worked as usual.  Has anyone else come across this?  It seems odd as overflow-x should hide the horizontal scroll bar?  Why would it effect the vertical?</p>
  
  <p>I have tried this on a test page and it acts as expected.  So it must be a combination of things.</p>
