Wacom has released new tablet drivers for Windows OS. I am sure Mac will follow shortly. I have a new Cintiq 24 HD Touch that hasn’t worked correctly since I bought it a few weeks ago. Wacom support tells me the new driver will fix the situation. I hope so.
To find the drivers, follow this link. Wacom Drivers
Remember it is best to uninstall the current drivers, reboot, install the new drivers, and reboot.
