Hi i am using maya 2011 and i wanted to animate my character using blend shapes(phonemes). i create a nurbs circle and assign the blends shape attributes to the circle so i can animate the character using the circle.

The problem is that i cannot key frame it by pressing S. Instead i have to select all the attributes and clicked key selected. It is very troublesome. I dont have this problem in maya 2010.

Anyone know why and how?
