What do you mean "overhand" method?
I think he means this: http://f.tqn.com/y/drawsketch/1/S/5/2/overhand_down.jpg
I had no idea anybody held a stylus that way, I assumed there wouldn't be enough traction and surface area for it to work. Thank you for the help! I thought he meant not laying your palm down on the surface because it's missing palm rejection software or something.
Yep Scarlett is correct, a lot of traditionally train drawers use the over hand method for better control. But a Wacom stylus can't tilt beyond 40 degrees.
I never use the new multi touch so I'm not sure how the palm rejection works though.
