title: Cannot load unregistered resource /.extlib/dijit/Dialog.js
body: <p>Domino Server running 853FP4 on Windows</p>
  
  <p>Same application running on two servers behaves differently. When trying to launch an xe:dialog from a partial refresh via a button I get a message in an alert box:</p>
  
  <p>An error occurred while updating some of the page. Could not load 'extlib.dijit.dialog';last tried '/xsp/.ibmxspres/.exlib/dijit/Dialog,js'</p>
  
  <p>On the server that works the dialog is displayed.</p>
  
  <p>If I request http:///xsp/.ibmxspres/.extlib/dijit/Dialog.js on the working server I get javascript source returned.</p>
  
  <p>On the server that isn't working I get:</p>
  
  <p>Cannot load unregistered resource /.extlib/dijit/Dialog.js</p>
  
  <p>All seems to suggest extlib hasn't been loaded properly. I recreated the updatesite just in case and that didn't help.</p>
  
  <p>Any ideas?</p>
