@GruensFroeschli:
MSN does work with the default settings.
Version, hardware, setup, did you install any packages, what did you configure? (even if you say everything is on default, you had to do "some" configuration)
Currently i'm using 1.2.3 RC2 based on FreeBSD 7.2 .. but previously I'm using 1.2.2 which also gave me the same problems as well
Hardware Specification:
Intel Pentium 4 3.0Ghz
1GB DDR400 Ram
2x Realtek Gigabit LAN card
1x Atheros Wifi card
