Quoted from glpinball:
My glass is fine never heard of that one.
It's as if the channel grooving is set too low or the playfield is sitting slightly too high. When I take the lockbar off, the glass does not naturally slide down. When I pull it down to remove it, the very edge of the glass hits the front of the cabinet about the coin door.I have to jimmy something under the glass ever so slightly to be able to slide it out safely.
