I’m not really sure but you could check this one out http://codex.wordpress.org/Function_Reference/wp_nav_menu
And I see your site FunFUnFunny has still way to go!
daxel11,
If you use Firebug, you should be able to delve into your code deeper, and find what you’re looking for. It will give you the div names and info for your menu. You will still need to find where to change the theme, but I’d bet it’s in the header.php file. Incidentally, I use a Mac/Safari and your menu just looks like it uses a .css hover rule. (Assuming your menu is the one “Home” link in the top right). If you’re using the fade, you might slow it down a bit.
