At first I thought this was maybe normal behaviour, when my macbook is connected to my emac or vise versa and one of them disconnects (goes to sleep, logs off, leaves the wireless network area in my house etc.) the other goes insane trying to find it, the beach ball appears and I can't do anything with the system until it realizes (usually a good few minutes afterwards) that it's not there anymore OR more recently it never recovers and I'm forced to power off . I searched google to find out if there is a fix.. but I actually couldn't find a single report of this even happening to anybody else (maybe because i wasn't really sure what to search for?) Anyway Does anybody know what I mean? does it happen to you too? can it be stopped? Thanks!
