I got if figured out, but I'm wondering if I missed something.
My first attempt was to put it at the end, but then it showed a finish button (they can cancel from warnings page, but not finish) and could find no way to tell the wizard that I didn't want a finish button (it was as setup page, not an official finish page).
I then tried it at the other end, as the first page, but then it wouldn't show a back button (I didn't try the ShowBackButton...found that later...maybe it would have worked?), which it obviously needed so they could go back and fix things. I ended up putting in a known location and writing a fair amount of code in the BackClicked and NextClicked event handlers to get navigation correct.
So is there some way to manage what buttons are shown, especially the finish button? I could find no property to manage this button at all (of course, I'm likely missing something!).
Thanks for the help...I'm getting there
