From what I saw Prototype/Scriptaculous aren't loaded at all. And please keep in mind this theme was release just to demonstrate what could be done with Fbox, Userstyle and additional Prototype based JS. It's clear stated we'll give no support and we don't recommend using it on production sites.

If you are experienced enough download CL Widgets plugin from here. Create your own widget and port all theme JS to it. If you load external ressources e.g adds, js services etc this could also increase your site load time.
