Hi Charlie. If this helps, I have the same issue. When I use my MacBook M1 with Parallels and Windows 11 Arm PixelCNC exhibits the same cursor behaviour. I always type in the coordinates such as canvas or layer sizes or positions as mouse control ends up with coordinates in the thousands. The other area is value adjustment eg simulation speed, can’t get anything inverted min and max. So I use it for convenience in the lounge room. Detailed work is on the PC in the workshop.
