I'm using Windows 10 on a fairly old laptop (no touch screen) and with a very old Wacom ET-0405-U pen/tablet, and Artrage v 3.5.12. I'm amazed the tablet still works at all, and in GIMP, it's also pressure sensitive, with qualification, but not in Artrage. I've looked online and tried many ideas from putting no_ink.inf into the Resources folder to playing with input preferences but nothing has changed so far.
I haven't messed with drivers because it's borderline working already and it was a fumble around to find drivers to get the tablet to work with Windows 10 to begin with, and that may tip the balance, so before I try that I'm putting the question out there in case anyone has experience with this particular set of circumstances - running the old Wacom with Windows 10 as well as Artrage. So one suggestion I haven't tried is downloading the Windows Vista drivers for the tablet.
