JB,
Went to Disk Utility and got the dreaded "your disk is ready to die" message. It said if my hard drive hasn't failed yet to back it up in a hurry. This HD issue could have been part of the Safari problem..it's been acting a little buggy as of late.
I've had this (12" Powerbook G4) for around 4 years and it's served me well. I've wanted one of the new MacBooks but couldn't justify buying one because this one did everything I needed and did it well. I guess I can now.
Thanks for the heads up.
