The little circle clip Hanger on the back of my BCD436HP seems to have broken off. The screw does not hold in place when I tried putting it back, and falls right back out. There was a small amount of black plastic around the base of the screw that seemed to be from the Hanger piece. Is there a way to fix this - use a longer screw or something, or can that damage the scanner? I guess the best bet would be to get a case with its own clip, but I liked being able to clip it to my shorts when in the house.
