On some of the upgrade browsers, there can be a most mysterious fault generated - "kore. loader not defined" or something similar.
The toolbox will place these two lines on the main page:
<script type="text/javascript" src="../includes/kore/kore.js"></script> <script type="text/javascript" src="../includes/jaxon/js/panels.js"></script>
All you have to do is reverse them:
<script type="text/javascript" src="../includes/jaxon/js/panels.js"></script> <script type="text/javascript" src="../includes/kore/kore.js"></script>
