Hi,

Many thanks for your reply and that is indeed helpful. I had suspected it was something related to W7 (though only to recent versions, since it doesn't appear to have been a feature with my new home W7 PC, only purchased last October). I did download the compatibility pack, but here at work, all spreadsheets created on my home PC are still showing with the orange 2010 icon, and opening in the 2010 'starter pack' mode, but no matter - I can at least access them and will have to learn to live with it (since I'm only in my London office 2 days a week in any event) and not to allow it to irritate me so much!

Thanks again.
