Got done with a crummy rental and when I opened up the door it was gone! I think there was crud on it and somehow fell off the arm. It was full so it couldn't of been misfiled. Never had another problem with it until this... Anyone ever pop the top and get inside? I know some mechanical jigsaws are hard to put back together....i.e Lasdiscs players so wanted to throw this out on the forum. If no one yells I will let you know how the surgery goes.
