Hello, I'm using Windows messenger with XP and keep getting disconnected after a few minutes. MSN has been no help they keep sending me to their help pages that I have already read 3 or 4 times. There are no error messages or warnings and I am still connected to the internet just booted from Messenger. Any help would be appreciated. Thanks, Bill System: AMD Thunderbird 1.2 512 ram Surfboard Cable modem through Linksys router Messenger Ver. 4.6 (XP version)
