The buttons on my tablet (Ugee s640) do not work in Photoshop

[Drawcarys]

The buttons work perfectly, but in Photoshop they don't work. The buttons are used for Photoshop shortcuts. The tablet is new and I installed the latest drivers and software from Ugee

I have zero experience with Ugee tablets, but if your driver/preferences look anything like this, have you tried adding Photoshop in the Application drop down?

Wew probably need more information to help you further. 

What have your tried?

Has it ever worked with Photoshop?

etc.
