IE5 for Mac - text link not recognised

I have a page which has text links (the enter buttons) contained in
absolutely postioned divs which themselves are
contained in relatively postioned divs. The links work fine on most
browsers, but IE5 for the Mac does not register these as links. A bit of a
problem if your a Mac user!

Appreciate your ideas. Link and relevent styles below.
