If you notice my menu bar has a nice bevel to it. Now if you go to one of the forums, and look at the search this forum drop-down menu, you will see the background image I have created to get my nice menu bevel is cuts a hideous line across the center. How can I make it so the search this forum drop-down menu does not use that background image but uses everything else?

What I have tried so far is to go into vbulletin-style.xml, copy the vbmenu_control template, paste a new template underneath it and change the variables I need change. Uploaded it back, and it doesn't work if I call the new template class.
