Loren, I read with great interest, as I am playing with trackers right now, I was monitoring your original topic waiting for an answer as well. And what you discovered helps me in my own tracker quest, so thanks for that.
I have done what you have before, ask a question, it never gets answered, and then I end up with a stubborn fervor, figuring the danged thing out anyway! Great job!
And thanks for sharing your adventure with this.
