[Dx4win] DX4WIN and the Rig Expert

I am having an issue with the RigExpert SD USB interface and DX4WIN. I have the RigExpert connected between a USB port on my pentium 3.0 ghz running WIndows XP Home and an FT 1000MP mKV. I finally got all functionality working through DX4WIN -- PSK31, CW, MMTTY and the FT 1000MP CAT all work great.  EXCEPT if I turn off the FT1000 and then some time later go to the Radio menu of DX4WIN and start the radio. Blue Screen on Windows. If I start and stop the radio -- same thing. The Blue screen talks about ks.sys which is the kernal streams driver used for i/o streams and audio.

The RigExpert only presents one virtual com port and I have it set to COM 8. In DX4WIN I have the CAT set to COM 8 and the CW interface set to COM 8. I think here in lies the problem (but I'm not sure).  If I disable the CW interface the issue goes away. But the RigExperrt guys tell me this should support DX4WIN and all its functionality so apparently I am doing something wrong. Does anyone know if DX4WIN can use the same comm port for both the CAT interface and the CW interface or is this an absolute conflict. I think the CW functionality just uses the DTR pin.

Thanks
