More post-divisi oddities

[Guy Stalnaker]

All,

Attached is a 12-measure  LP file snippet with four treble-clef parts 
plus piano reduction. The piano reduction works perfectly until it 
encounters a temporary polyphonic passage (TPP). There are two in the 
example, at mm.3-4 in the upper two voices and mm. 8-9 in the lower two 
voices. As you can see on compiling it (2.16.2) the first two measures 
are set in the piano reduction as expected, stems and rests in the right 
places and directions; LP reports no errors.

Starting in m.5 however, LP reports collisions for rests/notes in the 
upper voices and, as you can see, the stems no longer, as they were in 
the first two measures, go the 'right' way, up for the upper part and 
down for the lower part. The two lower voices continue to be set 
correctly until they, too, have a TPP in mm.8-9, after which they also 
are no longer set correctly and LP again reports collisions.

If I remove the TPP, the piano reduction is fine. I've tried using 
\stemNeutral in various places and other things, but nothing changes in 
the piano reduction.

The attached LP file has variables for both TPP and NoTPP, NoTPP has the 
divisi removed. There is a \score section for TPP and NoTPP. Simply 
shift the comments %{ %} to compile one score or the other.

Any help is appreciated.

Regards.
