Issue description:
After using alt+tab I can't paint. Left and Right click changes behaviour

Steps to reproduce:
I start armor paint
Paint on the defaut layer (with right click)
use alt+tab to go to some other window and go back
Now left click rotates the camera even if I have the paint brush selected. Right click zooms in and out

Pressing alt againt seems to fix the issue. But is not an expected behavior
