Chord inversions---I'm confused! (version 1.4.6)

[Alan Robert Clark]

Hi All

I am typesetting a bunch of chord inversion exercises, and getting wierd
results. The simplest test case is supplied below. 

(We're just looking at Triads here, looking at g ( < g b d > ) g/d works
fine = < d g b >, but g/b does not.)

Additional Q: why do my chordnames come out at the bottom, even though I
specifgy them first in the \simulataneous block?

Many Thanks, and all the best for 2004!!!

Alan
