I've found that every 30 min or less my MSN disconnects but doesn't tell me until I try to send a message. I can't work out why this is happening. I'm running MSN 4, OS 10.3.5, using Airport to connect to a Netgear WGR614 router. The windows computers in the house don't have an issue. I don't have any Mac OS firewalls running on my computer.
thanks!
