I have this issue that I can not use the CTRL+ALT shortcut to adjust the seize and softness of the brush with the wacom pen (!!!).
That shortcut is a standard in photoshop, while with the wacom tablet it tuns to a eyedropper, which does not pick any color or whatsoever..
It works without any problems with a mouse, though.
Does anyone have the same problem?
For me, this is a major workflow problem, hence it is more precise than anything else.
