In my previous email, I should have added that on the 'Edit' menu, the items of 'cut' and 'copy' and 'delete' are mostly greyed out and 'Review/remove individual data changes' are almost always greyed out and 'paste' is sometimes greyed out, otherwise I would have used delete or the 'review/remove etc' button to undo what I have done. Many thanks in advance for any help ---------------------- Best wishes, Anne
