As far as I know the mouse doesn't have drivers to update. In the past it has always worked fine with MSFT default PS2 mouse drivers.
It's a mystery.
I've gone back to the wireless mouse. It's still working normally.
Had to switch to the wired mouse to get a bios level drive cloning program to work. That one needs a PS2 mouse with some motherboards, but works fine with the wireless mouse on other mobos even though there are no mouse options to set in the bios for the mice on any of the boards now in use.
