(s) using the script. Please reinstate the notice first.
The AnyLink CSS Menu has only one level. It's code is associated with the page, at least some of its markup is in the page's source code. But I'm not sure where if at all it's actually used on the page.
In any case, the menu on the left doesn't appear to be activated by hovering. At least not initially.
Please restore the notice and if you want more help, please be more specific about what exact sequence of mouse actions need to be done in order to see the problem.
