G'day Peter,
hmm, but look what happens when the stem direction is "correct" for the chord (rest is now at -2047 and stem Down)
!NoteWorthyComposerClip(2.0,Single)
|RestChord|Dur:4th,Triplet=First|Opts:Stem=Down,ArticulationsOnStem,VertOffset=-2047|Dur2:4th|Pos2:-8,-4,-1,1,3
|Chord|Dur:8th,Triplet=End|Pos:-8,-4,-1,1,3
|RestChord|Dur:4th|Opts:Stem=Down,VertOffset=-2047|Dur2:4th|Pos2:-8,-4,-1,1,3
|RestChord|Dur:8th|Opts:Stem=Down,VertOffset=-2047|Dur2:8th|Pos2:-8,-4,-1,1,3
!NoteWorthyComposerClip-End
I do think this is a bug to be fixed rather than use a work around for...
