Menu nit working properly

[Amun]

Not sure if this is the right place - apologies if not.

I've been running a web site for a couple of years without problems. Following recent changes, I ftp'd the output as normal. The web site is at :-
http://www.mileham.info
The site has a menu at the top of the page. If one picks an option such as Groups then the page will display OK. However, if you then wish to switch this to another group, then the Groups menu seems inactive - until you go back to the home page. The menu can then be used again, for a single access.
The odd thing is that when I preview the site, eveything's OK. If I look at the output on the local computer, then eveything's OK. It's only when it's published to the web does it seem to go wrong.
I've tried different browsers and both Filezilla and the built in ftp system to do the transfers - no change.
I must be doing something stupid, but I can't see what.
The site is quite simple, so the wbs file is at :-
www.mileham.info/support.wbs

The menu seems to be working for me.
Did you clear your browser cache?
What exactly do I need to do to see the problem?

It's embarassing to say that clearing the cached data seems to have sorted out the problem. Something that I ignored as every browser seemed to be affected.

Many thanks,
