Yep. I went to the first Library I saw. I mean, I go to the closest brick and mortar library when I need one! Usually, the Main Library has more stuff!
I did notice you directed me to the user/Library, but I didn't follow the directions! This time, I didn't miss the turn.

I've moved the .plist for Word and Excel into the Trash for the moment. Now to do some testing....
Very strange... I edited my post (Full Edit) and got a 404 error; no permission....
Went back and used Quick Edit, and it worked.
Then tried a new Reply, and got the 404 again. Let's see what happens now...
Same thing. Trying Quick Edit again...
