George - the framelines do indeed shift to compensate for parallax, and
I've never had any problems framing accurately at that distance with either
of my M3s or M2 using any focal length of lens.

As you were shooting from 1.5m there really shouldn't have been any problem.

However, when you rack out a lens to focus really close, you're increasing
the focal length sufficiently for there to be a cropping effect - which is
why Leitz provide a supplementary close-focussing mark on the VIOOH finder.
I would have thought this would be more pronounced with short teles than
with a standard lens, but I don't think this is your problem.

Are you sure your rangefinder's not slightly out of whack, which would
affect the parallax correction too?
