Yes. The problem you described is likely a plug-in issue. I provided a link where you could update it. The menu will not work in Flash 4, but works in 5 and 6.
This should also clear up the issues you mentioned about all of the menus and the rest of the site. So, first thing I would do is go over to macromedia.com and install the new plug in, restart your computer and then see if it isn't showing up. Otherwise, I don't know what to tell you. May be an old OS or browser.
