[jQuery] Problems in a jquery drop down menu

[Borgir]

Hi there!
In this site:
http://work.r-m.me/termogreen/v2/
If you hover over a couple of times the Produtos's submenus (second
level menus):
- Energias renováveis
- Água quente sanitária
- Climatização
- Tubagens e acessórios
The sub sub menus won't appear (third level menus)...
Anyone knows why?
Thks in advance!
