Tiago, Mine did the same thing a few weeks ago - resetting every time that I went out into the cold to shoot. I think that I've found that a little extra turn of the screw that holds the battery door in place seems to have solved the problem. There's been no problem with resetting since then and I've taken several rolls of film in blizzard conditions. This is not the symptom of a low MF-26 battery (which also happened this fall)! If the batteries are low, the display will flash rapidly and randomly and you can't interact with it. Replacing the batteries causes a reset, no matter how fast you do it. This would suggest that even momentary loss of connection in the battery compartment will cause a reset. Thermal contraction/expansion might be enough to lose the connection when the temperature of the compartment is plummeting. Steve MacLeod N90s in Kalamazoo
