Ok, that also worked. I guess that means there's something in my .emacs or loaded packages that is conflicting with this?
I guess I can attach my .emacs file, which has been evolving literally over decades without my really knowing what I'm doing. I also went into "Manage Packages", copied the text out of that list, and flushed all the "available" lines, leaving the ones that are installed or dependencies.
