Kensington Trackball & Big Sur
Just upgraded to Big Sur and now I cannot get the Kensington TrackballWorks driver recognized in System Preferences. When I click on the TrackballWorks icon, I see this message: "Please authorize the TrackballWorks driver in System Preferences > Security & Privacy > General by clicking the Allow button."
The General pane of S & P shows "Allow apps downloaded from:" followed by an "App Store" radio button and an "App Store and identified developers" radio button. I've tried toggling the radio buttons both ways. I've reinstalled the Kensington TrackballWorks driver. I've tried the Trackball both on Bluetooth and with the USB dongle. I've powered the Trackball off for the suggested 10 seconds. No luck with any of these. Any ideas out there?
Thanks.
