RW not changing frequencies..argh

I have a rater annoying problemRunning winXP, RW installed, not a firewall problem.In SB RW is set to auto execute and channel change.When SB starts it will connect to unicom.However...When i then select ATC listing in SB and pick an ATC RW does jump to the foreground, disconnects from unicom, but somehow it is not able to connect to the selected RW ATC server...i'm not getting any warning about it...just RW not changing servers.When in FS2k2 itself and i select an ATC and press 'tune' from the servinfo gauge, RW will jump to front but will not connect to anything either.When i'm in servinfo 2 itself though and select any ATC and press 'join' RW jumps to the front and connects to the right ATC without a prolem...time and time again.I'm baffled.Something must be going wrong when passing the IPs to RW or something.Any clues anyone?
