Well, that solved the problem!  That is _exactly_ what it would do:
When in ALG entry mode, and I typed the division key, it would echo
'/()'.  And the x^y key would echo '^()'.  And when I converted a
decimal to a fraction with ->Q, the answer would show up as '20/(7)'.

It was _not_ the precedence flag; so your assumption of some weird EW
flag was correct - I entered the EW, exited, and everything appeared to
be back to normal.  [Question: Can you set and clear this flag manually?
I can think of times when it would be nice to have this on, since when
you press ENTER it strips all the unnecessary parenthesis anyway.]

I do have the capability to archive to my Mac; I will probably do that
just to be on the safe side! :-)

Thanks for the solution.  (If anybody would know, you would!! ;-)
I just wish I knew how it occurred, in case I discovered some weird,
esoteric bug! (uh, I mean feature... 8-)
