FWIW....

I've done some more testing and have a little more information.

It appears that there is a limit to the number of notes you can
copy into another folder without their being combined into a
single note. On one occasion, I was able to copy 10 notes; the
next time, it wouldn't accept 10 and I was able to copy only
9--so it appears that it may be size related.

So if all else fails, I guess I don't need to copy them one at a
time; I can maybe copy 7 or 8 at a time and be OK.
