Css Flyout Categories Menu troubles

[rwoody]

I have the Css menu working "nearly" perfectly with two small exceptions. Suggestions would really be appreciated. In IE6 and in Opera the left border is mission around the main box. Fine in FF. In all browsers I'm getting what appears a double line beteen Specials, New Products and All Products vs. the 1 px line. I've tried removing the bottom border, however it removes all lines except those. Of course then I only have a 1px line between the previously mentioned items. So I would think the bottom border for those items is being pulled from somewhere else... where I'm not exactly sure. I've gone all through the two style sheets and did not find anything that jumped out at me.

Any help would really be appreciated.

Here's my stylesheet_categories_menu.css
