You have your old WP8060 Pen tablet, it works as a mouse in your windows 7 or 8, but no pressure sensitivity??
This problem happens because your pen tablet's driver is installed automatically and let me say you something: it is not the right one.
You have to get the right driver from UC-Logic site, or from here
First of all, if you have to uninstall every driver in your system for your tablet,
then restart your pc with safe mode and let windows ignore the productor signatures,
when windows is opened; execute the setup program and plug your tablet, you will see a different tablet icon in system tray and when you right click it, you will see the pressure sensitivity is BACK ;-)
I recommend to save the driver some safe place, because you may need it in the future.
It works both for windows 7 and windows 8, both tested !
