Spell check in Evolution

OK, I have 1.4 up and running (finally) and all seems well except I can't get spell checking to work. I had this same problem in 1.2.x so essentially, I've never had spell checking. There are no dictionaries listed (Tools -> Composer Preferences -> Spell Checking) even though I have Ispell, Aspell and Gnome Spelling installed. How do I list the spell checkers in the aforementioned menu area so I can choose one? Many TIA's! Zach
