title: Preventing fb.ui() from scrolling the browser
body: <p>I'm working on a Facebook canvas page application using an iframe.  I'm using fb.ui() to create a dialog box for sharing however when the dialog opens, it's centered at first, then once the async call loads the dialog, it moves the dialog box to the top of the iframe and scrolls the browser to the top.  </p>
  
  <p>I considered using jQuery to reposition the box however I'd also have to scroll the browser position which screams hack to me.  Any suggestions would be greatly appreciated.</p>
