Navigation bar issue

Hi, zorro say me to talk here, there is a little issue with the navigation bar: When you approche from the bottom, the sub menu can take the focus too early and immediatly disapears. I have found that changing the css for "#gumax-nav ul" by raising the top value from 27px to 32px seem to work. (with that the sub menu appear entirely under the menu and not a little above it.
