Everything has been fine, until this morning, when I opened a Pages doc and began to work on a paper. For some reason, autocorrect isn't working––I've restarted and logged out twice, quit everything, even unchecked the "restore open windows after restart" button. Autocorrect still doesn't work. Checked/unchecked the option in Sys Prefs, checked/unchecked the option in Pages preferences. Any ideas?? EDIT: Reinstalling didn't do the trick. All misspelled words did not have the red underline underneath them. Weirdly, I can open a previously created Pages doc and it will have autocorrect and spellcheck work just fine. I was also using a custom template (just a blank doc with Times New Roman font) and when I switched to the default Pages Blank template, the red underlines appeared. Weird? I think so.
