D7000 secondary mode dial stiff/stuck
This has happened to me (out of warranty), and I've "fixed" it temporarily by giving it a good twirl - hold down the lock and rack it from end to end a few times... I hope that fixed it, rather than knocking something off it or working gunk into the camera, but it seems to work nicely now and the problem hasn't recurred.
