John: That’s great. I have laptops that run windows at work I could use. My mac pro and imac's at home all have bootcamp and windows 7. I am assuming I could load this program on multiple machines, that the only thing that limits the license is the serial numbers of the cameras. If that is the case for me the mac capability is just an annoyance and not a deal breaker.

I am real interested in your results. So far with Bob's results it is only a little promising, and looks disappointing for my longest most important lens.
