Hello, I have a powerbook g4 and i'm running tiger. I downloaded Safari 3b today. When I tried to install it the installer froze at the first few % of the installation progress bar. I had to force quit installer. I then tried to install it again and installer won't open. I restarted my computer after that and now when i go to click certain applications, they bounce once on my dock and do not open. For example: iTunes, iCal, Mail and installer will not open along with other random apps. I guess i'm lucky i can open my browser to ask this question. Can anyone help?
