z-depth rendering issue

Hey so this menu rocks and I really hope I can get this to work on my site.

However, the menu drop downs are being rendered behind my logo image (link) and thusly wherever that image is. This breaks the menus because they don't have mouse priority. I checked out the showcase site and your menu's work fine over the logo link. I am sure it is a theme issue as I am using iTheme which is not listed in your showcase.

I tried forcing the z-depth of the menu up, but its already set at 999 for the main ul tag. I also tried forcing the z-depth of the logo back, but once I go to -1 or less it shoots the logo behind the background image.

Any advice.

I also saw the patch and wanted to try it, but I dont know what to do with the patch file. How do I impelmnt it?

Thanks,

Brad
