coolmenu in Mozilla Firefox

[raenkrus]

Hello everyone,

I need some help because I'm using CoolMenu in a web page I've created, but it only works in IE and Opera. The menu doesn't work in Firefox and there are no errors in the Javascript Console.
It seems so strange because in another webpage the coolmenu is correctly displayed in Firefox...
Could anyone help me? The web page is http://www.rendenaeventi.org/?hl=home

Thank you in advance.
