I have a document with a lot of Latin names of plants in it. When I try to turn on the automatic spell-checking, Word says "There are too many spelling or grammatical errors to continue displaying them. To check the spelling and grammar of this document choose Spelling and Grammar from the Tools menu." But this means going through the document one "error" at a time, when what I need is to have it flag a typo as I type it.
I unchecked "Hide spelling errors in this document" and when Word gives me the message, it re-checks the box.
