Ok.. I'm almost trhowing the towel with Poser! I got Poserpro11 and using my iMac with 4TB and 32RAM with El Capitan. (Scared to upgrade to Sierra). Only Poser open working. When I hit the MATERIAL tab Poser QUITS! Poof!! Gone!... I hate this keep happening! I upgrade from Poser 9 because of the same thing besides slown rendering. PoserPro11 is great... BUT this is very annoying! Can anyone PLEASE help me understand this and what can I do.
