[jQuery] hover not working in IE6

[jQuery] hover not working in IE6


Hi, I'm having some issues with a drop down menu in one of my sites
(http://www.laseleccion.com.ar/argentina). While in Firefoz it works
perfect, in IE 6 y does not display the menu at all. It works in IE 7.
Any ideas what could be the problem?
Thanks in advance
