Options/Automatic Spellchecking is checked and the status line at the bottom of Composer shows "Spellcheck: on." Manually selecting Tools/Spelling shows the message "Spell check complete." But no mispelled words are marked, including nonsense strings like "lakjdfh."
ispell is installed. I can go to a command line and run the ispell program, which allows you to manually enter words. Correctly spelled English words get a response of "OK." MIsspelled words get a response of "Not Found." That seems to indicate that ispell is installed, the English dictionary is installed, and all is functioning normally. Anyone have a clue why it's not working in Kmail Composer? -- "A human being should be able to change a diaper, plan an invasion, butcher a hog, conn a ship, design a building, write a sonnet, balance accounts, build a wall, set a bone, comfort the dying, take orders, give orders, cooperate, act alone, solve equations, analyze a new problem, pitch manure, program a computer, cook a tasty meal, fight efficiently, die gallantly. Specialization is for insects." - Robert A Heinlein, _Time Enough for Love_
