Browser issues with Homebrew menu

I dont like using flash / java wherever I dont really need it, sadly that appears to be costing me a little on this website. One issues that has probably been here for some time is that some browsers are not rendering my CSS menu correctly, damn and blast to that...

The issue is that the first few links of the main page - do not function, more an annoyance than a serious issue, but now that I know about it - it needs to be fixed up.

The good news is that I have already written a new menu for this site, I just need to implement it. Shouldn't take too long.
