Just got my D5100 for Christmas. I have been reviewing the tutorial videos on lynda.com (Chapter 3, Session 2) for this camera. I noticed that they show the exposure compensation indicator on the LCD should move right/left when you move the command dial left/right while depressing the exposure compensation button.

When I perform the same steps my exposure compensation indicator flashes and the bars under the line stay the same. I also changed the exposure compensation via the menu route. The value never changes on the indicator.

Any suggestions? I've reviewed the reference manual on exposure compensation.
