Same thing here.
also the display assembly moves sideways when the keyboard is closed. A bit annoying but my own fault since ive drop the phone a couple of times.

And as a tip to those who got a problem with squeky sounds when touching the screen - tighten the screws behind the device. Remove the battery cover and tighten the normal screws. leave the torx screws alone though. - find the proper tightness for the screws so that the squeking stops. Made my n900 feel even sturdier.
