Hi there,
when c1 pro 3.7.2. was relased I downloaded it, but couldn't get it to work, so I had to go back to 3.7.1. When I saw that 3.7.3 was ready for download, I thought I could give it a try, even though that it was still an RC, and I have to say, I'm satisfied, white balance now works with my Nikon D2X.
Thanks Phase One,
