I am using DX4WIN version 7.01 in conjunction with a RigExpert interface box. I can get to the point of rig control and CW keying and sending, but if I click on Radio "Stop" or Radio "Start" my WinXP PC crashes and the Blue Screen indicates the file ks.sys as the culprit. I have tried various configuration set-ups both in DX4WIN and the RigExpert interface box driver but always with the same crashing problem. I had read somewhere that DX4WIN is not friendly towards Com port CW keying. Is this my problem? Or am I missing something in the configuration setups? Any suggestions would be greatly appreciated. Thanks, Tony N2SS
