Hey all, Sorry for taking a while to post back. I can confirm that "Tablet Pressure Curve Tool" does indeed work under Windows 7 Home Premium 64-bit! To get the pressure change to take effect you have to first alter the pressure curve and then restart the computer. "Tool is not designed for 64-bit systems, but it includes some basic support so it might work…" - If anyone else wishes to try this out on a 64-bit system to confirm that would be reassuring for other members. I'm going to assume under a 32-bit system you don't have to restart the computer? @dream3: How'd you go with the Compatibility Mode on Win 8? Are you using 32 or 64-bit?
