I have no idea how to edit this theme and it's becoming very frustrating. In other themes I've downloaded from you, I have a theme options menu in WP admin, but not with Showcase. If you visit blogsyndrome.com/marcophoto , you'll see that the flash menu has no content at all. not even buttons. What am I doing wrong? In WP admin all I have is 'customize, widgets, background, and menus' as options. customize does not give me much functionality.
