title: jquery dialog takes a while to open
body: <p>Currently we have a jquery dialog which contains 4 tables. Each hasa number of checkboxes in it:</p>
  
  <ul>
  <li>First box has about 10 checkboxes</li>
  <li>Second about 300 (one per country)</li>
  <li>Third and forth have about 100 each</li>
  </ul>
  
  <p>When I click on the button to open the dialog it can take a while
  IE7 = 10seconds
  IE6 = 15+ seconds</p>
  
  <p>Even chrome takes 2 seconds to simply open a dialog (a noticeable delay).</p>
  
  <p>Is jquery just not able to process the dialog open quickly when its has a dialog with alot of DOM objects?</p>
  
  <p>P.S. The dialog has already been initialized on page load, so I would assume the dialog open would be near instant.</p>
