I have Word 2000. When I run spell check it often highlights sentences I have written and tells me they are fragmented. The program, with the assistance of the most smug little git of a paper clip character, asks me if I want to do anything about it. Well, sure I would, if I understood what I had done wrong but after re-reading the offending sentenses they usually sound just right to me.
Tell us more, oh wise Mince, about fragmented sentences.
