1st of all: great template, still happy.
I have got one issue with the "Main menu"

(Hundesalon) (Hundpflege) (Hundeassecoires) (Hundenahrung)

The drop-down only opens, after I klick on the according "top-item".
The other top-items get highlichted, when I focuse the mouse, but the drop-down did not open...

Attached the site:

It looks like the mouseover is not working correct... Can you help me in this case?

Thank you very much.
