mail autocorrect spelling not working
i can't get mail to correct the spelling automatically as i type anymore. in system preferences i have the text set to autocorrect and also within mail there's a tick mark on "check spelling as i type". also in mail preferences i have the setting to check spelling as i type set. mail can see i've typed a word wrong and underline it but it won't autocorrect it even though the option to do so is turned on everywhere.
