Reschke the new drivers have worked fine on my system and I've not had any problems at all. The new THR_RANGE command is much easier then a string of messy LOCK and UNLOCK commands. I unistalled everything first, Cougar Drivers and FOXY and started afresh. Installed the Cougar drivers v2.02 then FOXY version 3 then flashed my stick with the new firmware and it all went smoothly.
