I am looking for comments/suggestions for cause/etc. for an effect I have
not seen before in my camera.
It manifests itself as one or two red squares ... one bigger than the other
... and a couple of times just
one square - that appear in finder while viewing the scene and also when the
image is reviewed. BUT they
disappeared when image is enlarged. They also seem to have vanished after a
few additional photographs.
I don't know why they appeared or what they were or what made them leave ...
and if they will come back again.
Any ideas? see here:

"Camera Function III number 4 turns the viewfinder red square(s) on and off
AF point display enable/disable turns the focus point(s) on or off in the
