title: Jscrollpane in a fancybox doesn't work
body: <p>I have a problem using the jscrollpane in a fancybox.
  Although after a nightmare of efforts I made the custom scrollbar to appear, it only appears the first time I open the lightbox. When I close the lightbox, and try to open it again, it looks like the jscrollpane finds no content and consequently doesn't run properly. </p>
  
  <p>Having a constant look at the firebug, I notice that when I close the lightbox, only the jspScrollable class (added by the jscrollpane) remains but all of the extra html is gone. When I open it again, the extra html is not created any more. It looks that this time the jscrollpane runs before the content is loaded.</p>
  
  <p>Here is my script: </p>
  
  <pre><code>    &lt;script type="text/javascript" &gt;
  
      $(document).ready(function() {
  
              $("a.enlarge-image").fancybox(
                   {
                     'overlayColor' : '#000',
                     'overlayOpacity' : '0.6',
                     'autoScale' : false,
                     'onComplete' : (function(){
                           $('#fancybox-content').jScrollPane();
  
              })
          })
      })
  
       &lt;/script&gt;
  </code></pre>
  
  <p>Any help would be much appreciated. </p>
