When I type "n's" + enter, it expands to something weird
I found the problem in AutoCorrect after much searching: somehow, the expansion of "he will" got in under a single "s" entry in AutoCorrect, so you were quite right. My first thorough search of AutoCorrect did not catch it, but my later search did. Thanks. My IT7 has been downloaded in the last 2 weeks, but the Typo Glossary did not contain that one!
