Aggers, I take it that you are still on Firefox.
It sounds as though you have inadvertently grouped two tabs - one for VV the other for the other site.
If you use the Bookmark/Favorites bar go to the VV link and right click on it. From the menu click on Properties. In the Locations: frame see what is there. Highlight and delete everything after
http://vocalvoices.gripsky.co.uk/ and click Save. This should reset the tab link.
If you use the Bookmark/Favourite list instead of the bar you can do the same thing.
You will probably have to re-bookmark the other site.
