Just had a look. The fix for MAC-183 was delivered in driver v. 10.6.5 back in March of this year.
Either the fix is only partial or you're seeing something differ. I suspect this would be unrelated to the new driver and/or macOS 11.
On the team's behalf, thank you. We decided to have Engineering engaging directly with customers here, in the Forum, whilst we work to restore functionality. Our colleagues in Tech Support are manning other channels.
And I'll also echo rosenstand's comment about the fact that you are actively commenting and answering our questions here, that seems to be very rare nowadays and it is very much appreciated
It was a disappointment not being ready when macOS 11 come out but we will continue to work until the new driver is finished.
You may be wondering what "finished" actually means. To us, we consider the driver as being done when we have restored functionality as driver v. 10.6.6 on macOS 10.15 with the exception of Universal Receiver support for wireless CadMouse pairings.
