title: blockUI works but unBlockUI Isn't
body: <p>I've implemented block UI as this request can take a little, time when the ajax request starts everything works as expected.</p>
  
  <p>But when the ajax request finishes and the msgbox is shown, the UI doesn't unblock! </p>
  
  <p>Any ideas?</p>
  
  <p>I'm using IE8.</p>
  
  <pre><code>$().ajaxStart($.blockUI); 
  $().ajaxStop($.unblockUI); 
  
  function ChangeCompanyState(companyId, state) {
      var parameters = "{companyId:" + companyId + ",state:\"" + state + "\"}";
      $.ajax({
          type: "POST",
          url: "Ajax/AjaxFragments.aspx/ChangeCompanyState",
          data: parameters,
          contentType: "application/json; charset=utf-8",
          dataType: "json",
          success: function(msg) {
              if (msg.d.length &gt; 1) {
                  alert(msg.d);
                  $.unblockUI();
              }
              else {
                  //Theres no message to process success.
                  window.location.reload();
              }
          }
  
      });
  }
  </code></pre>
