About twice a night, iChat will disconnect (though it'll still show me as connected). After about 10 minutes, it'll realize it's disconnected and bring up a dialog telling me it lost the connection. I can then close the dialog and reconnect with no trouble.
My computer's network connection seems to be fine throughout this.
- What might might be causing this?
- How to fix it?
- At least how to make it tell me more immediately when it loses the connection?
