Please keep us updated on your progress. I have loaded Vista Beta also and am curious if Ultra Hal can run on it.
Have you tryed the voice Recognition of the Vista system Yet? I seems very good. I have been afraid of overwriting it. I am trying to look out for voices that are compatible with it. I had not luck with the AT&T Natural voices. Vista won't load it.
Good luck with you program and thanks for experimenting for us all,
