title: Scrollbar of DIV with position FIXED is partly hidden behind window scrollbar
body: <p>I have a table of contents in my page (see <a href="http://www.pdark.de/haul/SceneFile-f446bc18-fdbc-42dd-bfde-2f501e2e7f73.html" rel="nofollow noreferrer">here</a>) with these CSS styles:</p>
  
  <pre><code>div.toc {
      height:38em;
      position:fixed;
      right:0;
      top:5em;
      width:21em;
      z-index:1;
  }
  </code></pre>
  
  <p>How do I have to change these settings to make sure the DIV isn't partially hidden behind the body/window scroll bar?</p>
