Chord Inversion Problem.

[AlanRobertClark]

Dear All. 

I am trying to put together a simple chord (triad) inversion exercise (piano).

Snippet:
\version "2.12.3"
accompaniment = {\easyHeadsOn \chordmode{
    c'1 c'/g c'/e} <e' g' c''>
}
  \simultaneous{
  \context ChordNames {
      \accompaniment
  }
  \context Staff {
     {\accompaniment}
  }
}

This produces the first two chords, as expected, but c'/e ends up producing <c'
c'' g''>, which is not in the way the second inversion would ordinarily be
played. Entering what I want produces (correctly an Eminor with a flattened 6th,
instead of the more usual C/E notation.

Any help will be appreciated.
Alan.
