My G4 Powerbook with 1 1/4 gb Ram kept locking up with that insipid spinning ball. I researched this and other forums looking for solutions. It all started after my son was playing HoboWars on Safari. I ran Disc Utility, Onyx, and TechTool Pro 5 trying to diagnose and solve the problem. I've been at it for 6 days. I have a ton of patience but I'm about to punch it in its face. I'm also purchasing new RAM in a few days. What I need are ideas on software that will prevent this from happening again. I have TechTool 5, & Little Snitch for maintenance and prevention. I use the Powerbook to run a small construction business on. I primarily use MS Word 04' and Gmail for bids, receipts, and communication with my customers. I would love any software suggestions and why you like the software.
