This is what the post was supposed to be.
Everything was going along nicely as I read this morning's feeds when suddenly I lost the category panel. I'm sure I did something but I don't know what or how to get it back. I went back to my prior topic - which diverged away from my problem which was solved; hence this new topic. I found the bit about whether the DB and INI files were in my program directory. They aren't.
Is there somewhere else they might be? Anyway, I have a recent enough backup directory:
Will just copying the most recent DB and INI files back to my program directory help?
Does anyone have a clue what I might have done to make the categories go away?
Thanks for helping. And for your patience.
