title: Maintain page scrollable while fancybox is open
body: <p>I have the Fancybox-Plugin V2 in use for a webpage. <strong>Now I have the Problem that the background image of the body and all background-DIVs (footer-section) moves slightly to the left when the Fancybox is opened</strong>, because the scrollbars disappear. I tried to maintain the page under the fancybox scrollable but get no succes. Has anyone a solution? </p>
  
  <p>The problem only appears on pages which already have scrollbars.</p>
  
  <p>These are the CSS-Settings for the moving elements:</p>
  
  <pre><code>#footer {width:100%;height:400px;margin-top:100px;position:absolute;text-align:center;
  
  #footer-wrap {width:900px;text-align:center;margin:auto;}
  
  body {background:url(images/hintergrund.jpg) top center no-repeat;}
  </code></pre>
