Hi,
From my experiance, I get an 'ired' error on Safari (whatever that is) and the page does not load, but not on Camino. Also, the iTunes store can never connect, and it says I have a network error. I don't see why Camino would work and Safari wouldn't.
I always get asked to enter a username/password in Camino.
I was just wondering why, even when after entering a username and password in System Preferences, then refreshing the pane, it appears I haven't entered one at all.
