I don't know if this will be news or useful, but, I have a tip. I have had problems since the 3060 beta, being able to uninstall and reinstall build 1970. I was getting a kernal flaw on starting 1970. I had, however, kept several preference and other items, as well as all the deleted program files. Once I emptied the trash, the went away, and I am now able to install and use build 1970. So, remember, once you uninstall, remember to empty the trash. Mike Tichon
