Z-index on Home Page Navigation

[gabe56]

I'm having trouble with the z-index setting on the home page of my site. It is cutting off the longer sub-menus of drop downs. It only does this on the home page. The z-index is set to 9999. This theme is called Scrollider from Woo Themes. The sites url is www.kuhnflyfish.com. I have tried adding a z-index property to many things in Chrome's developer tools. If you scroll down just a little bit on the home page so that the content wrapper is just below the navigation, you can see the problem much easier. I have even tried giving the content wrapper a negative z-index value, but that didnt work. Any suggestions would be greatly appreciated. Below is the CSS from the them un-edited.\[code\]ul.nav ul { width: 11.089em; visibility: hidden; position: absolute; top: 100%; left: 0; z-index: 9999 !important; margin: 0;}\[/code\]Thanks in advance
