Did you get this working? It seems like it’s working for me, unless I’m missing something.Whoops - I forgot to mention. It’s only in IE8 that it doesn’t work. It does work in Safari.

The menu does not work in IE8 because you are not using a standards compliant doctype:
The home page is missing the closing ’>’
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd"
and the inner pages have a short version which is not standards compliant:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
