Mouse click and hold not working

[tafurnell]

Running with two Windows 11 machines, everything is working perfectly except actions that involve holding down the mouse button (e.g. click and hold a window bar to move it, any attempt to resize a window, drag and drop). Sometimes it will appear to start to work and then it's as if the mouse button was immediately released as soon as the mouse starts to be moved.

I have tried changing all the configuration settings but nothing seems to resolve this behaviour. I am using a Cherry keyboard/mouse combination with a wireless dongle plugged into the keyboard USB. I assume it's related to this combination, as plugging in a wired mouse works without issue. It would be perfect if I could get this to work, so any advice would be appreciated?
