Can you please tell me what your Press and Hold settings are for Pen and Touch?
Hey there. It didn't make a difference whether it was disabled for rightclick or not. However I grabbed the latest feelit drivers that came out yesterday from Wacom, and now the problem has metamorphosed: it fixes the majority of the menu disabling brush issues, but now photoshop will sometimes disable pressure sensitivity until I tab out and tab in again. this is something that also randomly breaks in photoshop CC on my desktop computer at work (on a cintiq with windows 8), I have to occasionally tab out and tab back to get pressure to come back. Any suggestions or thoughts would be really welcome as it's really annoying when it breaks up my workflow.
Try clearing your Wacom preferences using their utility.
