Although most of the List have passed to 10.3.9 with no problem, I am sure that since I updated with the Combo, my system has been less stable. Eudora has quit on me twice and that is extremely stable software. Default Folder has quit about six times. Word twice. VPC once. Safari a few times. Keynote twice. And now Folding at Home core services quit, something that has never happened in the 4+ years that I have beeen folding 24/7, and I lost a project that had been running for weeks and had reached 35% completion. I think that this is sufficient evidence that all is not well, although I cannot be sure the blame is with 10.3.9, It just seems that way. regards, Trevor
