System Details:
Windows 10, version 20H2
mypaint-w64-2.0.1
Wacom intuos 4 and Mouse

Problem: Once i start using pen, after that 'mypaint' doesn't responds to mouse. I can only use scroll to zoom in and out with mouse. However right form the beginning if i use mouse it works until i click anywhere with wacom pen.

I have checked the devices setting in preferences where Mouse is set to allow any task. but problem still persist.

I have a similar issue. If I start mypaint and use the mouse for a bit, and then connect my tablet, it will only use the tablet like a mouse. This means that pen pressure does not work.
