I'm using Krita 3.3.2 appimage on mint 18.

Panning with the front button on my stylus stopped working. I thought maybe something was wrong with my stylus, but the even with the mouse middle button it stopped working. I tried to set the hotkey for the panning tool with 'space', and although that worked, then I have to reset my pen tool with 'b'.

Just to be sure it isn't something I did to Krita, I tried to reset all the hotkeys, but I don't see a way to do that. I know to go to configure Krita and shortcuts screen, but there doesn't seem to be a way to reset them to the Krita default.

Also, I just renamed my resource folder so that Krita will not see it, restarted, and the problem remains. The stylus button and middle mouse does not pan the view, and even the middle mouse does not zoom anymore. I also deleted my appimage and tried with a new copy.

And if you remove .config/kritarc?

Ok that seemed to work. Thanks, but also I admit to logging out and back in, so maybe that also fixed it.
