Aha!!!! I installed Bryce 7 Pro, beautiful program but in 2 minutes it crashed!! Ok, very esasy to reproduce. I went looking for some of my favorites mats from Bryce 5, I thought that by installing the older content they were going to be there, so I went to import and Bryce 5 and selected metals and import, they showed on my user gallery of presets and puff it crahed! It is reproducable. Is there a work around?
