Actually we don't bully people here. It's a free forum.
Your thickbox is not working because thickbox.js loads before jquery in the index.php file of your theme.
You must have edited something.... You should have something like:
<script type='text/javascript' src='<%baseurl%><%basename%>/site/js/jquery.js'></script>
<script type='text/javascript' src='<%baseurl%><%basename%>/site/js/cookie.js'></script>
<plug:front_lib_js />
...where plug:
<plug:front_lib_js />
is placed after
<script type='text/javascript' src='<%baseurl%><%basename%>/site/js/jquery.js'></script>
As for the first question, the menu gets created dynamically - if you know php you can edit what you want in ndxz-studio‚Üísite‚Üíplugin‚Üíindex.php
Otherwise if you want to affect how things appear and look then you can affect the menu via css in your style.css.
PS. Loved the "Bob Ross Tubing Bob Ross Tubing" painting :-D
