2011 Draft Analysis question

In older versions of SW when you would use the Draft Analysis and OK the model would stay colored red/green and constantly change as you modify the model.  I used this a good deal when working with injection molded parts.  In 2011 I find that after I OK the Draft Analysis the colors no longer stay.  No matter what I do with apperances, remove all, different display states etc I cant get the draft colors to stay on the model.  I am running 2011 sp1.0.  Is this an issue or the design intent of this feature?

Thanks
