I create blend shapes in seprate seprate files. and then import all of them in main rigged file but when I create Blend shapes and move the sliders there is some transformation in main mesh. then I copied the blended face on main head object and then freeze it their and delete history also. but some values comes in Vertices of blend shape which is not freeze at all. How to fix this problem . tell me please.
Please clarify. Freeze does indeed fix this porblem but t its also casues this problem, question is rather where the ojects are located when you freeze.

Implausible, either your desciption is wrong or your misunderstanding something.
Offcourse theres a slight chance thers a bug in maya 2012, but ist much more prductive to assume there is not because the implications would be so monumentous that you dont want to go there. In which case youd need to prove this.
