...a complete uninstall of the software and reinstall.

That could be a disaster, so I’ll stay away from that option.
I have now disabled spelling, so I’ll just have to be much more careful with my typing and my proofreading, I suppose.
Thank you.
I have used Mozilla Firefox as the web browser specifically BECAUSE it has an automatic spell checker for every text-based reply field in every web page I use.
No problems with Mozilla, nor its library, nor library-add applications. (You right-click to select the proposed corrections from the popup list.)
Haven’t ever used Opera, won’t comment.
