RadialMenu now lets you remap the 2 buttons on the pen to Right Click and Middle Click. It also supports Hover Click, which is a must for artists. This mimics Wacom Pen button mapping and turn the SP3 into a Cintiq killer. I've already done some Mudbox sculpting and it's really great. I was able to sculpt while on the subway without the need for a keyboard.

I just downloaded the latest version of this app (jan 26 update) but it would not run on my system (just got a crash popup everytime I try to start up saying the program stopped running). I downloaded version
RadialMenuSetup_x64_0.4.4.316.exe and got it to run, but can you tell me where the setting for hover click is and which version you use? I don't see it anywhere in the options to enable it
update: ok from the link I installed, it turns out there is no setting and hover click is automatic! But I was a bit confused because the settings under remapping are different:
Button 1 = the sp3 pen's top barrel button
Button 2 = isn't assigned to any of the sp3 pen's stylus (would have hoped it would work with the purple tip button but it doesn't)
Button 3 = the sp3 pen's bottom barrel button
