Has anyone ever noticed how some soft top frames have a tendency to sag in the middle above the door glass? There's a hinge in the top frame in that area and it will tend to make the frame sit lower in the middle than at either end. When you roll the window up the glass will hit in the center before it goes tight into each corner and no amount of adjustment will fix it.
If you've encountered this problem, what did you do to fix it, or can it be fixed?
