I just noticed that Wacom has a new update. The driver information said this:
“Driver supporting Intuos5, Intuos4 WL, USB versions of all Intuos4 (PTK) and Intuos3 (PTZ) pen tablets and the Cintiq 24HD, 21UX, 12WX, 20WSX,DTU-2231, DTU-1931 and DTU-1631 pen displays.
Save the file to your computer and then double-click on it to launch the installer.
Be sure to uninstall any current tablet driver installation before installing. If you have any questions, please contact Wacom Technical Support at 800-922-6613.”
I am unsure if the driver is posted for other regions; it is available for the Americas.
