wacom + mac + adobe + BTT issues

Describe the bug
I'm having an issue where my Wacom tablet (cintiq 13HD) behaves as though I'm clicking and dragging, even when I'm not. This issue stops when I quit Better Touch Tool, which is a shame because I'd like to use it! Itt's the same issue as described here:
