css drop-down menu

[PaintedSwan]

Hello all, :)

I recently came across this wonderful CSS horizontal drop down menu - http://www.sperling.com/examples/menuh/ ...but wanted to adapt it to use rollover images instead of simply colors. So far what I have works in every browser tested except IE6. Does anyone have any insight as to why the images for the parent and top-parent divs don't show for the resting state, only the rollover state? The problem is only viewable in IE6:

I'd like the menu items that have expandable content to have arrows in their resting state, which can be seen in FF, IE7, etc.

Thanks in advance,
~Swan

My description up there ^^ is quite vague. So I'll illustrate a bit more clearly with screenshots. :) The one on the right (IE7) Is correct. The one on the left is IE6. Any insight would be appreciated.
