As soon as I press a different letter, like going from "C" to "E", a word immediately begins and is displayed from the "C" group, when I want to choose a word from the "E" group. Of course, when I finally do choose a word from the "E" group, that word then replaces the "C" group word running and all is OK.

Not until I actually get to "E" and choose a word from "E", should a new word begin.
