Hello JulioPorben,
If you haven't done so already, I recommend installing the driver for your third party graphic tablet. Even though Windows 10 is great at "Plug n Play" so that you can use your devices without having to hunt down a driver, it is recommended to use a driver provided by the device manufacturer to enable full functionality of your device with Windows 10.
I hope this helps, let us know if you need further assistance. Thank you.
Hi BravoMan,
The tablet came with two drivers, one for the display and one for the input, but the input /is/ what treats it like a mouse, not like a pen tablet
If it helps i'm using a Parblo Coast 10 Graphics Monitor
