Hello, I use Photoshop CS6 often for digital painting. Gradually over the past year and a half since I bought the creative suite package, I've encountered more and more minor glitches. The most glaring is the loss of some hot key commands - mainly the bracket keys.
The bracket keys stop responding after only a couple seconds of painting. But, I can get them to work again if I move my cursor up and click on a blank space on the tool bar. However, immediately as I paint on the canvas again they go back to being un-responsive.
It really disrupts my workflow, and is incredibly frustrating. I run on a Mac, now with Yosimite (Problem occurred before updating software) and a Wacom Intuos 5 medium.
Awesome, thank you. That has seemed to resolve the issue!
Thxs for the question and answer. I just started having this problem after upgrading to Yosemite. This fixed the issue for me.
