I’ve pasted your email into a new document and switched to Aspell as my current spell checker backend in LyX.
Stephen, That's interesting. I use ispell here rather than aspell, but I don't recall having this problem years ago with LyX. Perhaps it is a spell-checker issue. I'll see if there's a way to contact the ispell developers or a way to add words to that dictionary.
I don’t know how to fix it and I think it’s not a task for LyX development.
Not if it's not related to LyX code. I'll find how to edit the dictionary. Thanks, Rich
