title: Question about SimpleModal jQuery plugin -- possible to re-center after initial open?
body: <p>my problem has to do with <a href="http://www.ericmmartin.com/projects/simplemodal/" rel="nofollow noreferrer">the SimpleModal jQuery plugin</a>.  I have no problem opening the modal window, but once it opens it stays where it is [centered] on the screen, however its contents are changing, making it taller and therefore no longer centered.  Is there a simple way to realign it so it becomes centered again?</p>
  
  <p><strong>EDIT:</strong> I think it would help to explain my problem by showing two screenshots: <a href="http://img707.imageshack.us/img707/4051/modalbefore.gif" rel="nofollow noreferrer">before</a> &amp; <a href="http://img260.imageshack.us/img260/1215/modalafter.gif" rel="nofollow noreferrer">after</a> -- basically I am using jQuery's <a href="http://api.jquery.com/slideUp/" rel="nofollow noreferrer">slideUp</a> &amp; <a href="http://api.jquery.com/slideDown/" rel="nofollow noreferrer">slideDown</a> functionality to hide the credit card form depending on whether the user is paying via cash/cheque or credit card.  Obviously with the credit card fields the height of the container is increased.</p>
  
  <p>I tried adding <code>$("div#modal-element").setPosition()</code> in a callback element of slideUp/slideDown but to no avail -- in fact <code>setPosition()</code> is throwing a JS error because apparently the function doesn't exist.  I always tried adding the autoResize option and setting it to true.</p>
