For what its worth, I appreciate hearing the full spectrum of reviews. If SR1 is working for you then there is the possibility that points me toward looking into my own directory for something that might have gotten erases or corrupted. E Frontier Tech Support has replied that my "blue channel corruption" problem was part of a problem they thought they had solved with SR1. Well... Bopperthijs: Regional settings, you say? Interesting. As I am in Australia. I'm not totally clear how that makes a difference but if it is causing my problems can it be fixed. E-F currently is only suggesting work-arounds that I already explained I was using. I would rather not work-around but have it work. Writing to a psd shouldn't be so difficult in the 21st Century. IMO
