I'm looking for a replacement part that's part of the pointing stick on my I4000. It's the black piece labelled "goes on first" in the picture below. The "goes on second" piece is the rubber nub (in this case yellow), and it fits overtop of the black piece. The black piece, which is plastic, snaps onto the little white "stick" which is attached to the keyboard. It has broken twice (cracked in half) and I've been able to fix it with crazy glue but I don't know how many more times I can glue it back together and hope it keeps working. Anyone know how I can get another one of these things? I have no idea what it's called. I have extra of the coloured, rubber pieces but not the black, plastic ones. I e-mailed the Parts customer service people a few days ago but didn't hear back.
