Issue I331 [7,8,critical,resolved]
  Acceleration error in overlap of electrostatic PA with magnetic
    PA of higher grid density.
  Reported by simonp-20061206.
  Description:
    If an electrostatic PA overlaps a magnetic PA and the magnetic PA
    has a higher grid density, then the electrostatic accelerations in
    the overlap region are incorrectly multiplied by the ratio of the
    two grid densities.  This is a fairly serious error that
    surprisingly was not reported earlier, though in practice the
    necessary conditions might arrise in only small number of
    simulations assuming magnetic fields are not normally simulated to
    higher accuracy than electrostatic ones in SIMION.  This error was
    first detected when Data Recording reported a KE_error value that
    was enormous, indicating energy was obviously not being conserved.
  Affects: 7.0.0-7.0.3 and 8.0.0.
  Resolved in 7.0.4 and 8.0.1.
