I have tried the 64bit version and found it wouldn’t work and then read the forums that it is a known bug. I switched to the 32bit version and after placing several zSpheres I needed to delete one. I used the cintiq programmed side button and nothing happened for a minute or so and then the program crashed. I cleared out my settings and reset everything on the cintiq, rebooted the iMac, opened the Cintiq and then ZBrush and the same thing happened again. The program works fine on the iMac running v10.8.5 but it is just slower using the keyboard and mouse to sculpt anything.
Anyone else having this problem?
