title: Facebook FB.Connect.requireSession() stopped working
body: <p>I've got this page that calls:</p>
  
  <pre><code>FB.Connect.requireSession(callback)
  </code></pre>
  
  <p>and in the callback are all the things I need to do after I know the user has a working FB session. It used to pop up a new window, which would ask for permission (or to log in, or whatever) then close and call my callback function. Now, however, it opens a window, asks for permission, and then sends the user to the canvas page on Facebook IN THE POPUP WINDOW. I have no idea what could be going wrong because I'm just using the documented JS apis, and not even doing anything fancy.</p>
