Subject: [Leica] Focusing problem!

Hi!
I have used my father's M4 for a while now. The greatest camera I ever used!
However, I do get a lot of shots which are back focus. Especially 
evident when using the tele-elmarit at short ranges. At first I though 
that this was just my own fault, not paying enough attention when 
focusing. Well, I now pay a lot of attention when focusing, and still I 
far too many back focused shots - never too short focus.
I got tired and set up a home made test target and to my surprise, it 
seems like the camera focuses about 1-1.5 inches too far away. This is 
true for all lenses I tried. 35, 50, 90 and 135mm. The strange thing is 
that the range finder seems to work at infinity, where the two images 
line up perfectly.
The small arm that connects the range finder with the lens in the camera 
  seems to get stuck some times. But only for very short periods of 
time, and it snaps back when I rotate the focus ring on the lens.

Do anyone know what could be wrong? I bet you all know how annoying it 
is to see that great portrait coming back, with perfect focus on the 
person's ear. Crap!

Thanks
Arvid
