I've just updated the driver of my wacom bamboo, and I have no more zoom with the first button of the pencil, which is assigned to panoramic/scrolling.
If I remember well this button was activating the zoom, isn't it ?
Now it moves the canvas like the second button (right clic).
Is there a way to get back the zoom, or maybe it's a bug with the new driver ?
The driver file I installed is cons511-1_int.dmg
