Thanks for responding.
Yes I had indeed checked all of the setting to be certain there were no overrides.
When I went out again to check the meter I discovered that it was completely Kaput...back to Leica for repairs. Rather amazing in that the camera was so rarely used. I suppose there is no direct correlation between the number of readings and the "life" of the meter. Nevertheless, I admit to being surprised that a meter so rarely used would have to be replaced.
Incidentally, have you noticed how the prices of Leica R glass are increasing...some of the zoom lenses are off the wall in price....
