Downloaded 10.2.6dmg, restarted, screen froze and loads of diagonal lines appeared. Was forced to reinstall 10.2 to get my Blue G3 to work again. Any way around this problem?

Hmm ... I've not heard of any problems with any of the 10.2.x upgrades. After the clean install, try downloading any necessary firmware and then running the 10.2.6 combo upgrade. See if that works without a problem. Another suggestion ... if you have enough space on your present drive, try partioning it as desired. Use one drive for your every day OS X usage. On another, small partition, keep a second OS X System Folder. Whenever a new update comes out, always install it on the second System Folder and make sure it doesn't do anything screwy. If it doesn't, install it on the main X system folder. If it does, whoopdy- doo, because it's not the one that you use day-to- day. If you ahve two hard drives installed, it makes that easier. ----paxcirc.a-

Have got a second hard drive which I'll try installing the upgrade onto. Thanks for your help.
