Thankyou MarcioAB. I wonder now many have tried large animation files. I`ve used 5 figures i.e.winterQueen x 4 & standard male. All have walk paths with animations and frames set to 300. When launching the keyframe editor it takes about 8 secs to fully display. Any action within keyframe editor also takes about 8 secs to update. making it unuseable. This happens in both OpenGL & Scree software mode. No problem in P5 works a dream. What going on?
