Were the things which seemed mis-framed approximately as far away from the 
camera as the point of focus?  Note that the parallax compensation is of 
course tied to the rangefinder...  if you happen to be making a photo in which 
some objects important to the composition are much farther or closer than 
whatever's focused on, it may behoove you, if you're taking a leisurely photo, 
to rack focus to their distance to see where they'll lie relative to the 
framing lines.

(Please excuse this statement of the obvious, but sometimes the obvious is 
only so in retrospect...  I didn't always take this phenomenon into account.)

Was your framing problem related to the above, or some actual mechanical 
imprecision in the parallax-compensation mechanism?
