> I have a PC running bluetooth v. 2.1 using a Widcomm stack (126.96.36.19900) released on 7/21/08. I also have a different PC running Bluetooth v. 2.0 running Widcomm stack 188.8.131.5200. The Bluetools software I am using (version 184.108.40.2068) works fine with the older stack, but there appear to be problems with the latest stack. Do you have any insight into this problem? Thanks - Ravi.
