On my gf ibook, she has recently updated to 10.4.3 and since then Safari wont log on to the internet. The first time she started safari since the update, the keychain question popped up and I guess she just cancel it out. So since then she can't use safari. The internet still works since she can use AIM and Mail, but not safari. I tried deleting the .pref file, but that didnt work. So I have no idea why.
