title: FB:SHARE Plugin (on FB Tab) Not Showing Up In IE Only
body: <p>I'm using the FB Share plugin on a facebook tab, so this is just inside the body tag:</p>
  
  <pre><code>&lt;div id="sharebtn"&gt;
  &lt;fb:share-button href="path-to-redirect-url.html"&gt;      &lt;/fb:share-button&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>The redirect is a go-between page with the meta information I want the pop-up to be filled with, and it forwards the user to the full address of the tab the user is sharing.</p>
  
  <p>basic fb.init:</p>
  
  <pre><code>&lt;div id="fb-root"&gt;&lt;/div&gt;
  &lt;script src="https://connect.facebook.net/en_US/all.js"&gt;&lt;/script&gt; 
  &lt;script&gt;
    FB.init({
      appId  : '12345668blahblah',
      status : true, // check login status
      cookie : true, // enable cookies to allow the server to access the session
      xfbml  : true, // parse XFBML
       channelUrl : 'channelurlblahblah.php', // 
      oauth  : true // enable OAuth 2.0
    });
  </code></pre>
  
  <p>So the thing is, it works properly (display) in all browsers when you view the tab contents in isolation, ie: </p>
  
  <pre><code>http://www.atdesigner.com/c/byf/fb/recipes/
  </code></pre>
  
  <p>And it works if you view the tab (via iframe) in facebook, in all browsers except, you guessed it, IE.</p>

  </code></pre>
  
  <p>Why isn't the share button showing up in IE, when viewed through the FB iframe?</p>
