Many thanks to most of you. I have tried everything that has been suggested without result. I have now cleared Office & re-loaded it with the same result, so perhaps it is an issue with Windows 7 which does seem to come with "issues" such as an almost total lack of compatible low end scanners. rans6andrew's comment was singularly unhelpful. You must be very bored. When I bought office a few years ago, I had never heard of Open Office even if it did exist.
