Vista Style Builder

I have been working on a theme for a few day now and have come to something that is driving me absolutely nuts !

I cannot find the background hover color or image for things like "file,edit,view,tools,and help" also for Organize,share with and right click pop up menus . when you click on them the pop up menu color is correct but when you hover over them it turns white and I do not want it to , where can I find the setting that changes this color or image ........ see screen below .



Thank you in advance !
