Menu different in IE and Firefox

I’ve copied a menu code from [URL=http://exploding-boy.com/images/EBmenus/menus.html#3][B]this site[/B][/URL], but it doesn’t appear the same in Internet Explorer 6 and Firefox 1.5.

Here’s what I mean, that’s the menu on the left:

[B][URL=http://img1.imagetitan.com/img1/1/22/siteie.gif]In Internet Explorer[/URL][/B]
[B][URL=http://img1.imagetitan.com/img1/1/22/siteff.gif]In Firefox[/URL][/B]

I have just changed the menu title and image from “menu14” to “menu2”.

This is just an additional problem I’ve been having since I started this site and I can’t find a solution for this one.

I’d be very glad if you could help me out!

The code is attached.
