Minor glitch, when in review mode, after magnifying a picture, any press of a d-pad button or the magnify buttons zooms in to max magnification.
Note however, this doesn't prevent you from un-magnifiying the image or using the D-pad to move around (i.e. : it's not really a major problem).
Running the camera with an ML card in, but bypassing ML one-time displays correct behaviour.
Replication: #Press the Play button - enters review mode #Press magnify once - image zooms in one level (as expected) #Press any key on the D-pad, or either of the magnify buttons - //zooms in to max magnification//
From this point, it's repeatable - you can either press play to go back to flipping through images, or zoom out and d-pad to another image, press magnify once, and the next press of a d-pad or magnify button will push you into max magnification.
