Tina, the subject of this e-mail is statistics... I have shot with both Fuji 
and Leica. I reluctantly have to offer a couple thoughts,

1.this simply does not happen. (bouncing in a truck or changes by curious 
kids playing is different).  If this were to explain all, then no exposures 
are oof for any of the usual reasons
2.when you shoot with the leica, for each image, the settings will be reset 
in any case.
3.people in the past have noted that a high % of difficult leica exposures 
are oof...this has ranged from perhaps 10% to a majority of times....

(the common problem that can be very hard and annoying to find initially is 
a change in the switch on the front, but one learns, as Frank Dernie 
mentioned.)
