Thank you for your suggestion, Graham, but it didn't work. I did what you
recommended: I opened Normal.dot, moved the Clipboard toolbar from its
obsessive docked position so it would float normally, added a text space to
the document and then deleted it, save the result, closed Normal.dot, closed
Word, re-opened Word, hit Ctrl-C twice, and, lo!, the Clipboard toolbar was
RIGHT BACK IN ITS DOCKED POSITION.

To say this is frustrating is an understatement! I very much appreciate your
thinking about this and offering any ideas. I'm more than willing to try any
suggestions. Many thanks, again.
