Query: Dumb DOS program, no DVORAK support.

How hard would it be to support DVORAK? A hundred lines of code would probably do the trick, since no new graphics would be needed. Just cross-reference the keys to make finger positions right, and you're done. They're resting on their laurels, selling a clumsy DOS program that takes over your monitor as if it were still 1989.
