I created a small scene using Spectral GR for my atmosphere. I worked all morning manipulating the lights. etc. and did not have a crash. I closed it and worked some more and did have one crash, but I am not experiencing the same problems as the others. My resources did not falI lower than 92% when I did check them. I am using XP Pro. So far it is workig as well as the pre-release without the last update. I just installed it this morning so I need to work on it some more. I am not using anything from other programs except billboards from Xfrog.
