Err i have that problem too. But mine isnt while using messenger but while doing anything
It was mainly whilst installing ZAP (Zone Alarm Pro) .... its ok now. So im guessing there mabbe a conflicting program or something. Do u have 2 Antiviruses or 2 firewalls or something (well not like a firewall + windows firewall cause windows firewall shuts down when another firewall is running )
Plz see if you have some conflicting programs
