I'm new to dynamic blocks so the answer might be in my face. But I created a semi complex block of a chair. Now I want to put that chair in other blocks (with tables, stools, etc.) I've noticed when I insert the chair into the other block, I have the grip controls in the block, but when I test the block (in 2010) I lose the individual chair grips. Is there a way to turn the nested grips on, as well as the host's grips?
