Title says it all. The autocorrect feature does not work in Mac Mail. It's selected to correct as I type in the mail preferences. Autocorrect works fine in other apps (like text edit). In mail it just underlines it in red and nothing else. It's a new 13 inch MBP (regular display). I have reset the parameters when restarting the computer. I have also tried multiple settings in mail (and system wide) to fix this. It's not my computer, so I don't want to have to reinstall Mountain Lion or have to start over with the mail app (unless it's very, very easy to do so, including not having to recreate all rules and smart folders). Any help would be greatly appreciated.
