Hi everyone,
And sorry if this has been answered already (I made a search) : I recently reinstalled all my machinery, and sure I missed something : I’ve lost all pressure parameters from my cintiq 12. They’re available OK for all other apps (Adobe, Corel, Luxology…), but not ZBrush.
Somebody able to tell me what I’ve missed, or messed ??
Quad 6700 CPU, nVidia 8800GTX, 4 Gb RAM, Dual Samsung226 "plus"Wacom Cintiq 12WX
Hello and sorry for troubling. I made a new search and found the answer : We have to reinstall the wacom driver : ZBrush likes being the first on the spot… 
Thx to soakedroot
Well folks. I’m afraid there’s still issues I can’t figure out. In fact I have to reinstall my driver (pro605-7_int.exe) each time I start my computer : Pressure parameters work for all apps except zbrush, if I do not re-install.
No doubt some vista thing I do not know of
Anybody could help. No urging : doesn’t take so much time to dble-click this install
Thanks anyway
Try uninstalling the driver, restart your PC, then defrag your drive and also your registry (delete any empty keys that are found). Then restart again, then install the driver. then restart the computer one last time then start zbrush and see if that works. If it doesn’t then I would complain to wacom and microsoft both.
It seems like it is a Zbrush or wacom problem though, not microsoft. Cause if it is being recognized by other apps, then windows is doing it’s job.
Good luck. 
Yea, some drivers are funny like that. I had a Nvidia video card driver update (think it was the 6800 gt card) a while back that only worked after I uninstalled the old one, restarted my PC and then installed the new one.
