Hi,
since the 4.2.1 version of Krita is out and I installed it, i'm not able to paint on a canvas. It does work with version 4.1.7 and older.
It's possible to paint in Krita version 4.2.0 while pressing the button on the surface pen, which stands for right click.
I think in Krita v4.2.0 and higher Krita doesn't recognize the pen as a left click as normally. Changing the preferences didn't help me, either.
Can somebody help me, please?

Regards ihaveaproblem

edit: solved
