Menu images?

I just noticed that all of my toolbars have the option "Image is inherited by submenus" selected, and I do have a toolbar image defined that's shared across all toolbars. However, all of the menus that pop up have a plain white background. Am I missing something here?

Nevermind, got it: It was the option "Use Office 2003-style in toolbars" that was overriding things.
