wave functions and time
I think there is a mistake somewhere in some of the contributions.
The wave function does evolve in time, and the partial differential
equation which describes this (schroedinger's Eqn) mentions
the potential energy field and h-cross.
 I haven't looked at this stuff for a while, but I think it would be
found that S's Eqn for a photon outside potential wells tends to show
that it moves along at velocity c, as you might expect.  So would
a suitable energetic electron (though S's Eqn isn't really integrated
with relativity).  Nevertheless, as Donald Chan says, the lonely
electron could be observed at A and then a short while later a very
long distance away, because the evolution of the wave function will
give (rather small but non-zero) values idefinitely far away at
once.  I wouldn't lose any sleep over it though, myself.
