A couple days ago, I bought a Wacom Intuos4 tablet. I had this tablet working perfectly with GIMP the day I bought it, but the day after, I plugged in the tablet to see that all of my customized buttons were reset to the originals. I recustomized the buttons in the Control Panel, but now GIMP won't recognize the pressure or shortcuts on the tablet, no matter what I change in Preferences. Anyone know how to get it working again?
