The Symmetry for IK enabled limbs doesn't work, either left to right or right to left, for both arms and legs, when IK is on PP 2012 won't do it correctly, it will apply the symmetry to the shoulder and forearm but not the hand, same with the legs, it will copy the thigh and shin symmetry from one leg to the other but not the feet, this however can be solved turning IK off but this is a waste of time at least for me since I like to work on posing with IK turned on at all times, and this started happening since the first SR.

Also the Undo option from the Edit menu will not catch all the changes or it "forgets" all the changes made from time to time.

What gives?
