Oh geezus. I'll take a look. I need to reinstall 10.6 on one of my machines or get safari 5 some other way. Kind of a bummer that Apple was unable to give 10.6 users Safari 6. I'll see what I can do. I may just be able to hide that menu completely when in fullscreen mode. HTML5 fullscreen is supposed to do this automatically but clearly its not doing it in Safari 5.
