Css drop-down menu

Hello all, :slight_smile:

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
