title: Facebook Canvas Application iFrame Size Showscrollbars Issue
body: <p>I am using Facebook C# SDK in my ASP.net application.
  I have an iFrame application whose iFrame Size set to Showscrollbars.
  <img src="https://i.stack.imgur.com/OMKqj.png" alt="Settings">
   The application was working fine till yesterday, but today the iFrame is not stretching to its width (From the documentation Facebook's iFrame width is 760px <a href="http://developers.facebook.com/docs/guides/canvas/" rel="nofollow noreferrer">Link here</a>). The page in my application's width is set to 95%. So I think its not a width problem in my application.

  I have to use Showscrollbars option for my application.
    Did facebook Changed any settings for the iFrame Apps? Help please.</p>
  
  <p><strong>UPDATE</strong> Looks like facebook broke something or they are trying to get rid of scrollbar options. I have to change my application to use AutoResize Option. I made the following changes to my asp.net application and it is working fine except one issue (see at the bottom of the question)</p>
  
  <pre><code>&lt;head runat="server"&gt;
    &lt;title&gt;&lt;/title&gt;
    &lt;script type="text/javascript"&gt;
      window.fbAsyncInit = function () {
        FB.Canvas.setAutoResize();
      };
    &lt;/script&gt;
  &lt;/head&gt;
  &lt;body&gt;
  &lt;div id="fb-root"&gt;&lt;/div&gt;
    &lt;script src="//connect.facebook.net/en_US/all.js"&gt;&lt;/script&gt;
    &lt;script&gt;
       FB.init({
                  appId: '12345678', //replace with your facebook appid
                  cookie: true,
                  status: true,
                  xfbml: true
                });
    &lt;/script&gt;
  &lt;/body&gt;
  </code></pre>
  
  <p>iFrame stretches vertically when the content increases. That's cool but the
