I have a problem with my D90 I'm unable to figure out. Whenever I take a long exposure with my D90 (say, for 10 or 15 seconds), when the shutter closes again, the info display on the camera reads "Job nr" and the camera is non-functional. If I turn the camera off and back on, it then "saves" the image normally, and pulls up the review photo on the display, as if nothing had gone wrong.
So what's going on here? I don't have any modifications on the camera, I shoot in programmed auto most of the time, and it's a stock 18-105mm lens.
