Plugging in my new hermstedt webshuttle modem while my ibook is on makes my screen crash. It is a scary multi-lingual message telling me to turn off my ibook. If I want to plug it in, it seems I have to do so while my computer is off, and hope I don't crash once I'm on. If I want to unplug it, it seems I have to go to internet connect and disconnect, and for the split second that it's disconnected, and hasn't yet tried to reconnect, I yank out the modem, and that seems to work. Is it supposed to be this delicate?
