Also make sure you don't have lock actor turned on with IK. That's like mixing dynamite and nitro. Also there used to be an old bug in the P3/p4 days that caused this effect. It was a storageoffset value set wrong in the file. You can run your cr2 through morph manager and save with the storageoffset bug fixed flag turned on. Also, when you implement your MT and set it to 0, does it do this? If you start dialing upward does it get progressivily worse? if so then its your MT.
