Any app that uses a network connection (browsers, F@H, iTunes, iChat, etc.) has been having problems opening -- unless I'm on my AirPort connection. They open, but then I get the beachball for 2-3 minuted before responding. The strange thing is, it only happens on modem and Ethernet connections: my PPPoE over AirPort connection lets them open just fine.
