Placed a (debug) in .emacs just before the loads for my-*-file.
Then did some tracing, but nothing was helpful.  However, after
that, the error message from desktop-read about desktop file
already in use showed at bottom of frame.  Strange thing is
that before that message showed in some sort of widget.
So I answered to use anyway.  Then exited emacs, and now
no error message occurs when emacs restarted.

I've no idea why.
Anyone have a clue?

Larry
