transmenu plugin css help

Need help with transmenu plugin for dropdown menu. CSS is kinda screwy but what a great plugin.

Looks beautiful in firefox, in IE6/7 there’s too much space between the links, the navbar pushes into the next row and messes up the layout – example

i THINK this could be a simple css fix, but ive been through everything and cannot fix it.

Please Help! Launching this blog very soon.
