In IE6.0, once you log in there are four drop down menus at the top of the page called "British Isles, Europe, Global, Help and information". When I log in on Opera 7.2 they aren't there. I can still access all the info from the main page, it's just much easier to navigate with the drop-downs.
At the bottom, it says "Javascript must be enabled to use the drop-down menus". As far as I can tell it is enabled, but some other option somewhere must be blocking it?
