Most of time when I receive a file from another Mac in the LAN via iChat's Bonjour service, the file doesn't arrive in my Mac…or if it does, the file is just 0 KB… I need to close and then open again iChat in the sending Mac to get the file. It is really annoying. Turning on-off the Firewall doesn't solve it, and yes, my firewall entry for iChat Bonjour traffic is 'on' in both computers.
