Thanks Mark. Yes, I though about putting a small hook under the top bar behind the foamboard that would hold the chain close up against the frame. The more simple solution would probably be, as you suggest, to attach the wire further up. How close to the top should I go? The frames are in portrait orientation and the wire is now at 8 1/2 inches from the top.... What about putting rubber stoppers on the bottom corners of the frame....this may alleviate the problem somewhat....
