I'm retired after 40 years in the banking industry. After I retired I went back to college for one year to get my degree. My mother is very ill, as well as she recently got home after surgery. I am taking care of her almost 24/7. Until she had surgery I was a volenteer at a local hospital 15 to 20 hours per week. Until my mother had surgery I helped out at my local church. Now ask me that question again? What do you do?
It sounds like the frames are loose in one or more dimensions. Try to discern in which dimension the looseness is and see what would be needed to tighten the frames up in that dimension. Possibly gently bending more curve back in to the frames in one dimension might be all that is needed. I would email Post 4 and ask them.
