I have a java drop-down menu that works fine. However, the menu stops working as soon as I activate Lightbox 2, Lightbox Gallery, or jQuery Colorbox. I've activated and deactivated all combinations of the plugins, as well as deactivated my other plugins so I know these are the culprits.
*EDIT* I should let you know that this only occurs when I'm on single post, or post-summary. If I'm on a 'page' or the home page I have no problems.
