title: Reopening modal dialog very slow on production server
body: <p>I have modal dialog boxes on my site. </p>
  
  <p>They work perfectly on my development machine and my test server. </p>
  
  <p>On the production server though, they work properly the first time they're opened, but if they're closed and reopened... </p>
  
  <p>In Firefox they work perfectly. </p>
  
  <p>In Chrome they spin for about 2 minutes, then open. They do this every time they're opened after the first time.</p>
  
  <p>In IE they spin for about 2 minutes, then open. They do this every other time after.</p>
