I really don't know if this is the appropriate category for my question. I have a Bamboo Pen & Touch that I use for drawing and animation. I am able to configure the pen buttons to some actions, but I want to configure the Express Keys of the tablet. When I go to Wacom Graphics Tablet in System Settings, and go to Map Buttons, this is what I get:

It shows no buttons at all, although my tablet has 4 buttons. How can I solve this??
