title: How to set pagetabs height to auto with no scroll bars?
body: <p>My page tab always has scroll bars if the page in the iframe is greater than 800px. I see there is a 'set canvas height to fluid' in that advanced setting but that dosen't seem to help. I've tried other suggestions like adding</p>
  
  <pre><code>   &lt;script type="text/javascript"&gt;
      window.fbAsyncInit = function() {
      FB.Canvas.setSize();
     }
     // Do things that will sometimes call sizeChangeCallback()
     function sizeChangeCallback() {
      FB.Canvas.setSize();
     }
     &lt;/script&gt;
  </code></pre>
  
  <p>but doesn't seem to work.</p>
  
  <p>Any ideas? </p>
