After playing JJ2 online for a few minutes; not sure about other games, but in my game it happens; my internet (ADSL) just goes offline but leaves the indicator in the system tray that it is still on. No internet things work though (ICQ, IE, messenger, other games) and I can't reconnect without restarting my comp.
I got windows 98 and no firewall.
I'd really like to play again but this problem has kept me from it a few times now... thanks in advanced folks.
