Sorry for continuing this argument, but the problem isn't changing your OS language ot English (UK). I've done that, it hasn't worked.
The problem is that the only dictionary provded by MS-Word is the English (US) version, and to get the UK version we have to search through a Microsoft website.
I could rant about the lack of need for there to be any differances in the spellings in any case, but that might come over as being slightly racist (sorry).
