I read this on the warning page of a Japanese site the other day...
Your browser, really too old.
You are not running a dhtml compatible browser therefore this funky side
menu thing is not going to work. Your loss. It's really cool. It is a little red menu that
pops out of the page with black text which turns white as the mouse goes over the top. In
Internet Explorer it even animates as it opens. But, you'll have to take my word for it.
Upgrade to IE 5, or Netscape 4.5 (it won't look as good as IE 4 or 5 though).
Otherwise use the emergency menu at the bottom of the page. It is put there for technogically backward people who are determined to make the life of a web designer that little bit more difficult.
Hit the back button and try again.
