Oh, right, that is helpful.
It might be that the eyes are becoming misaligned. I had that problem on my Dark. The eye covers that were used didn't hold the eyes in place very well, so when jostled, they didn't always point at one another. I fixed this by wadding up some paper towel and sticking into the cavity on the inside of the eye cover.
Detentes do seem like a likely culprit, although the 2004 and later detentes were a lot better than the old style ones.
