When the F100 is set for Closest Subject Priority, the autofocus sensor
display is turned off (p. 39 of manual, righthand column). Further, in spot
metering mode, the center sensor is always used when the camera is in
Dynamic AF Mode with Closest Subject Priority active (p. 45 of manual, last
line).
For what it's worth, Nikon made some curious decisions when configuring the
electronics of the F100. This is one of them. Why they would think anyone
would put the subject on one spot and exposure calculated from another, I
have no idea. It's clear from the other capabilities of the F100 and the F5
that the electronics are capable of shifting the spot meter with the subject
area, so this design decision must have been made for a reason none of us
can fathom.
