As a follow up I had some of my tech friends test this and this is what we found
It looks like there is a browser compatibility issue. It works fine in:
Safari 3.12
Firefox 3.02 on Mac
Firefox 1.5 on Linux
Internet Explorer 7.0 on Windows XP
But not in:
Internet Explorer 6.0 on Windows XP - You don't even get the tabs on the main page.
not sure what the issue is with Explorer 6.0 but will try and find, thanks for all you help, George
