Hi GerZS, i think you know what you have to do, figure out a combination that will work better. But I think maybe you dont know the keyboard and drag combinations and thats why you have that strange pen setup. if you press ALT+CTRL and drag the brush horizontal you adjust the brush size, dragging vertical will adust the hardness. Get used to doing that and you will love using the brush that way.

yes, this is how I adjust the brush tip, but with the combination Alt + Right click (which I mapped to the pen.) and drag. The combination Alt + Strg (CTRL on US Keyboard) stands for "duplicate layer by dragging", at least here on my german keyboard.
Anyway, I now found a solution and put "Alt + right click" as a combo command on the pen. Did not consider that ... With this my problem is solved. Thanks for the help and suggestion !
Cheers Gerhard
