Hi all, I’ve been having this same problem. I’m glad I’m not the only one, although EXTREMELY frustrated. I just updated the driver to 6.3.8-2 but it didn’t help. I tried adjusting the sensitivity settings for the Wacom but that doesn’t help much either. I’m using a Wacom 5 with 10.9.5 with PP CS6. The jumping only happens in PP.
Has anyone heard from Wacom about another fix besides updating the driver?
