Resolved. Thanks. Why, I don't know, though. I opened the Normal.dotm at a location I had checked twice yesterday, before and after rebooting teh machine, and this time it showed the defective version, easily corrected, and now what comes up from Windows menu and taskbar shortcut is fine.

(I say "at a location," because, due to a computer refresh last year at a service place, I ended up, as I once did before, with two apparent users in place of one. I have left them, because I don't want to lose any possible info by deleting one (yes, I have backups, but who want;s to check every file?) and it's reportedly a tricky Windows issue.
Everything works fine, mostly; this little glitch was a rare gremlin.)

Thanks to you both!
