Been having this issue for sometime now and decided to come here for solution if there is one.
My problem is that my pen will not respond until I use my mouse, then go back to the pen and it will then work. This happens each time I change a tool in photoshop. For example, if I chose the brush tool and try to draw, my pen is unresponsive. I have to use my mouse to apply the brush, only then when I use my pen will it work. I then change my tool to eraser and my pen will not work until I use my mouse to earase, then I can pick up my pen and it will then work. Is anyone else having this issue?
I have updated my photoshop to version 25 but had to go back to version 23 because of so many bugs in 25.
