Do you have any expressions for those layers=3F If so, there was a kn= own issue where the UI becomes sluggish in CS6.

I converted the nulls to = lights using David's script and the problem was the same - worse even.

This is very difficult to understand. There is no= thing to render - no layers except nulls. All layers are turned off. Th= e nulls are static and don't have keyframes.
