Ever since installing Panther, whenever I open Sherlock, it causes the internet to stop working for an hour or so before I can get it to work again. Basically, I click on Sherlock and it just sits there with the black spinning thingy and after that, if I try iChat, Mail, Safari, IE, etc, it just sits there as if the Ethernet cable isn't even plugged in. I check network settings and it lists my IP address and everything, but it just doesn't seem to work unless I turn off my PowerBook for a good half hour and mess with my router or just plug in my old PowerBook and mess with the internet and then plug it back into my Aluminum PowerBook and try it. Also of interest, does that "Renew DHCP Lease" button do anything? I click on it and it just doesn't seem to be working.
