title: BlockUI jquery plugin keeps page blocked after "back" button. Opera/FireFox
body: <p>I use jquery <a href="http://jquery.malsup.com/block/#overview" rel="noreferrer">blockUI plugin (v2)</a> and call <code>$.blockUI</code> when user submits a form. Web page smoothly fades out and new page appears. That's ok. But when user presses "back" button in opera/fire fox he observes fade out page with hourglass mouse cursor that is completely blocked. </p>
  
  <p>Chrome/IE visualize page ok.</p>
  
  <p>What would you suggest?</p>
  
  <p>Thank you in advance! </p>
