hmmm. after I merged the two halves, the blend shapes still seemed to be working fine - it was just when I bound the skin and started moving limbs that things went wierd - the face still makes a smile but when you move the arm vertices start flying on the body. Is this because the body is trying to go to the blend shape body? Should I have just made a blendshape for the head, rather than the whole body? When you make blend shapes, do you keep the head and body as seperate pieces of geometry? Also do you make the blend shape on just half and then duplicate? sorry for so many questions.

My head is hurting. I need a smoke.
