Message app is no longer auto capitalizing first word of a sentence.
I have a Mac Bood Pro (retina) running El Capitan. Recently I noticed when I'm in Messages that it no longer auto capitalizing the first word of a sentence. I've looked in preferences and can't find a way to change it back to auto capitalizing. The auto cap works perfectly on my iPhone.
MacBook Pro, OS X Mavericks (10.9.3)
