I had a similar problem with version one and again with 2 which is still happening with 2.2.1 I can edit about 5 photos and then it crashes, usually on develop (I am using RAW photos) or save. As the problem with 1 seemed to be RAM, I upgraded to 16Gb and that solved it until the upgrade to version 2. I have been tracking this and it seems that as I develop photos the ram being used goes up as if when as I save and close one photo it is stored or held in RAM. My spec is well above the minimum recommended but PCs are known to use whatever RAM is available. Not sure what I can do about this. Upgrading to 32Gb may not solve anything. Any suggestions?
