Bless your rotten cotton socks!
Thank you for the courtesy of your efforts.
For anybody else with a similar problem, I DID find that Micro$oft has published a READER for doc files. You can't edit them, but they do read. There's a similar reader for their .xls files, too.
It was remiss of me not to have advised when I discovered this but frankly, I was too urgently interested in making the transmaps work - getting a grip on those now.
Eventually I'm going to HAVE to spring for a version of Office - waiting until Win7 is released.
