Hi. about a week ago I suddenly started to have network/connection issues with some applications: Tweetdeck (adobe air) Widgets that require internet (weather etc) Safari (not Firefox) iTunes store Mac Software update (these are only ones i have come across so far) I have never had probs with these before and not sure what has changed for this problem to occur. Each app tries to connect and either hangs, timesout our causes a network error popup to occur. I have checked the firewall and is set to accept all. It only seems to be some apps, plenty of other apps that require connection are working fine. Anyone else having this problem and or know solution? Doing my head in! thanks b.
