Since upgrading to v1.10 Beta, I've been experiencing an anomaly with my Flex Control. About once a day, the Flex Control will stop working, requiring a shutdown of SSDR and a reboot of the Win10 computer. The knob is setup on COM99, and otherwise works fine. When the lockup occurs, the mouse wheel continues to function, and looking at Device Driver, no obvious problems are shown. I have a second Flex Control on order to pair with the first using SDR-Bridge to control the 2nd knob. It will be interesting to see if the same problem occurs with that knob.
