i am using a Surface Book with Photoshop for painting. I'm sure everybody knows the combination of holding down the ALT Key while holding the right mouse button then moving the mosue to resize or soften the brush.
In the past it was possible to do this also with the pen of the surface book. So you had to press the ALT key, hold the "right mouse button" on the pen while draging the pen to the left or right.
But since some time it has stopped working and just the color sampler appears when doing so.
Has anybody a solution for my problem? i tried allready resetting photoshop, updating everything on windows and some other stuff.
