Hello,If I try to start squawkbox, with "Use Roger Wilco" checked and without enter a IP for RW server, my system lockup (win98se, adsl) and I have to re-boot, looks like SB can

Not sure about dialing in the controler freq. and getting RW to change, but you should be able to double click on there listing under "ATC" and then it will change RW for you. Also, when you start up SB and it says it can't connect to the rw server, no biggy, it will still switch when you double click on the controller listing.

I have Roger Wilco setup to default to "Unicom" when I first log on to Squawkbox. Then after I lookup the online controller in the ATC directory; then it tunes automatically to that frequency.The IP I have set as my default is 209.95.104.44
