A few tips for Wacom tablet users:
- Turn on Force Proportions to ensure that when you draw a circle it is actually a circle, not an ellipse (in my case: Control Panel -> Wacom Preferences -> Pen -> Mapping settings)!
- Turn off windows special (annoying) feature:
Control Panel -> Pen and Touch -> Press and Hold -> Settings, disable the feature.
- Customize the pen buttons:
I use Right Click for the lower button and Middle Click for the upper button.
- If you have trouble with the tablet cable:
Set the orientation to Left Handed (or vice versa).
