title: Facebook Access Token Missing
body: <p>Following instructions to acquire FB access token for desktop app using the manual Login workflow is not producing an access token for the default successful login.</p>
  
  <p>If I add the "user_likes" permission (I'm sure some other permissions would work as well, but "email", "publish_actions" and "public_profile" don't) to the login URL scope argument (thereby engaging the user's agreement to provide that permission), I receive an access token.</p>
  
  <p>E.g.:</p>
  
  <p>This URL - </p>
  
  <blockquote>
    <p>https: //www.facebook.com/dialog/oauth?client_id={0}&amp;redirect_uri=https: //www.facebook.com/connect/login_success.html&amp;response_type=token</p>
  </blockquote>
  
  <p>Produces the following response URL - </p>
  
  <blockquote>
    <p>https: //www.facebook.com/connect/login_success.html
    <em>&lt;--NOTE the missing access token</em></p>
  </blockquote>
  
  <p>If I modify the request URL to include "user_likes" as follows - </p>
  
  <blockquote>
    <p>https: //www.facebook.com/dialog/oauth?client_id={0}&amp;redirect_uri=https: //www.facebook.com/connect/login_success.html&amp;response_type=token&amp;scope=user_likes</p>
  </blockquote>
  
  <p>Produces the expected result URL -</p>
  
  <blockquote>
    <p>https: //www.facebook.com/connect/login_success.html#access_token=REDACTEDREDACTEDREDACTEDREDACTEDREDACTEDREDACTEDREDACTEDREDACTEDREDACTEDREDACTEDREDACTEDREDACTEDREDACTEDREDACTEDREDACTEDREDACTEDREDACTEDREDACTEDREDACTEDREDACTEDREDACTEDREDACTEDREDACTEDREDACTEDREDACTEDREDACTEDREDACTEDREDACTEDREDACTEDREDACTED&amp;expires_in=5108029</p>
  </blockquote>
  
  <p>What am I missing?</p>
  
  <p>I'm using the WPF WebBrowser control on Windows XP (yes, if you can believe that), if that helps?</p>
