I can't find anything wrong, but then that's why it works fine in FF and IE7. I think it might be that IE6 is ignoring the height and collapsing. If that's true, then the horizontal line should be consistent in color and length with the border on the div? I would think that the content of the div would force it open though. I hate these problems!
The XHTML is at http://beta.earthchronicle.com
The markup for the two navbars is at the end of the file.
The CSS is at http://beta.earthchronicle.com/ECBeta/EC.css
I've titled the CSS relevant to the navbar's structure and it's the second section of the stylesheet. If you need to see the border information, all my visuals (colors and borders) are in the Sepia.css file in the same directory.
Take another stab at it, and let me know if that's useless to you and/or you're still having trouble with it.
Whatever you can do or dream you can, begin it. Boldness has genius, power and magic in it. Begin it now.
