This sounds like a Wacom issue are you sure your pen settings are correct for ZBrush 4r8? I've had no issue at all with the buttons I'm working witht the same tablet as you are.
He's just awesome! He's really clear and understandable, also not boring at all, I'll be going through all the episodes, maybe I'll take out my wacom, will be the first in a while.
I have been working making some concepts in photoshop, directly with the wacom. The idea of making small models with painted textures was pretty funny, so i'm in this funny project with Peter :)
i'd like to make it clear my texture didnt use that at all, infact mine came from an interview photo of morgan freeman + my wacom painting (for stuff like hair).
i've been using this at work and a little at home - http://www.abstractspoon.com/ i prefer a piece of paper with written notes myself as well tho, or postit notes stuck under the wacom overlay.
draw loads of concepts, buy a wacom, make some low poly art and textures (DS style) get all that down, befor you jump into high poly modelling and sculpting
Often small strokes and such cause the wacom to pause for a split second. This didn't happen normally before I changed the sensitivity and when I first got it. This is really bugging me, and it happens in all programs including windows itself
I CONSTANTLY press CTRL+Z in real life...I have undo binded to one of my wacom pen buttons, so I try to press buttons on my normal pencil all the time, and on the desk or the paper with the other hand.....xD
Ugh, this looks so similar to how I currently draw in Photoshop. I just for the life of me, can't get the same stroke I get on paper with a Wacom, and I've been trying for over 20 years. :/ I'm totally getting a Cintiq.
