I use a Wacom Intous drawing tablet and have set my controls so the bottoom 4 buttons are tools, i have zoom in and out set on the Function keys at the top.
Since gesture doesn't really work well with ArtRage, i have set the circle button/wheel thingy to change brush size (but i have to select Brush size first)

Unfortunately it's very easy to press the circle button down, and then it changes to the next command which is Rotate canvas.

I change brush size a lot on the work i'm doing so i am regularly accidently changing the circle wheel to Rotate command in instead of Brush size.
which results in my accidently rotating the canvas.
Its frustrating.

Any recommended solutions?
