title: jquery blockui plugin doesn't override the default 'waiting' message
body: <p>Can somebody please help me with these questions about using the jquery blockui plugin (http://jquery.malsup.com/block/#)?</p>
  
  <ol>
  <li><p>Why doesnt's this work?</p>
  
  <pre><code>$(document).ajaxStart($.blockUI({message: "wait..."})).ajaxStop($.unblockUI);
  </code></pre>
  
  <p>If I just do this:</p>
  
  <pre><code>$(document).ajaxStart($.blockUI).ajaxStop($.unblockUI);
  </code></pre>
  
  <p>it works, but I want to set override the default message with my own. This doesn't work either:</p>
  
  <pre><code>$.blockUI({ message: "wait..." });
  </code></pre></li>
  <li><p>I've been able to override the message with this:</p>
  
  <p>$.blockUI.defaults.message = "wait...";</p>
  
  <p>but if I define a div in my page and pass it to the message property then it doesn't work, but according to the documentation in the plugin's website it should:</p>
  
  <pre><code>&lt;div id="loadingMessageBox" style="display: none;"&gt;
      &lt;img src="../Images/spinning.gif" /&gt;wait...
  &lt;/div&gt; 
  
  $.blockUI.defaults.message = $("#loadingMessageBox");
  </code></pre></li>
  </ol>
  
  <p>Thanks.</p>
