title: How to position facebook popup window?
body: <p>I'm using the facebook button below</p>
  
  <pre><code>&lt;fb:login-button perms='email, user_photos, user_birthday, user_online_presence'
          autologoutlink='true'&gt;&lt;/fb:login-button&gt;
  </code></pre>
  
  <p>Each time I click it its opening popup window floated to the right. How to set it to center?</p>
  
  <p>I tried on clean page without any styles tried in different browsers and all the time just login window floated right</p>
