Hi Ken,

There is actually two statements but i think I know the one you mean. 
First the sensitivity to the warm spectrum is well known but only 
important if you are photographing with slide film where that is the 
predominate colour. Normally it is not an issue.

Now the meter memory problem. Yes I have experienced it but always with 
my old Nikon F2a. The Nikon F and F2 meters (except for early ones) 
meter wide open so, if you accidently point a f1.4 lens at the sun, the 
Cds cell starts hallucinating big time.

The MR-4 meter has two ranges so in bright light the meter is shielded 
quite a bit. Also the meter is only powered for a brief period. These 
two reasons are probably why the MR-4 meter is not prone to the memory 
problem. If you point a powered MR meter in low light mode at the sun, I 
would say it would want to lay down in the shade for awhile before being 
accurate again.
