[SOLVED] No Menu 2 background using WP menus, WP v3.3, Ata 3.7.3

Hi, I've run out of ideas on this issue, and none of the fixes I saw in other posts seemed to apply. Hopefully it's some easy thing I overlooked. Thanks in advance for any help.

I have the category menu under bar2, which is under the banner, which is under bar 1, which is under the page menu. I have WP menus turned on, and have mapped %page-right (Menu 1) to a menu I called Menu One, and have mapped %cat-center (Menu 2) to a menu I called Menu Two.

The problem is the the second, %cat-center menu, which I've tried to give a background color to, and when the color failed to extend past the menu items, I tried making it a background image filled with that color. I put the image in my Ata images folder and have tried various means of getting the background to work, including adding the following line to both the Ata CSS/HTML inserts (there are no other menu items defined there, so no cascade issues I can detect), and also adding the same line to css.php, in the div#menu2 style. I've tried this with and without defining the color, as well.

I should note that this solution worked prior to turning on WP menus.

Again, any help greatly appreciated...
