Thanks for following up.
Automatic Spell Check is working in certain sections of the same document. And not in others. For instance, I can type a nonsense word, clearly misspelled, into one part of the document, and it is flagged as misspelled. In another section of the same document, it might not be. In some documents, the auto spell check works for the entire document. In no instance has every word been flagged as misspelled.
I've never uploaded a document to this site, but I might be able to. Problem is I'll probably have to create a new document. All the current problem documents are the pages of a nonfiction publication slated for publication early next year. Creating a new document to illustrate the issue could take a while. If it doesn't appear, don't assume I've solved the problem. I'll see if I can duplicate the issue but the document might be a bit incoherent, at least as far as content.
