Umm...6 bars of music of which 4 show the problem and the other 2 are
necessary to show err the problem.

Pretty tiny to me. If I don't have the 4 bars the problem isn't there, if
I have 5+ then the problem is still there. So the issue *could* be some
weird modulo4 bars of music-thing or some internal logic that seems to
fail at small measure counts. I don't know (if I did I wouldn't be
reporting it).

As far as I was concerned, Possibly and Yes. I could use *100000000*3/8 or
*2*3/8 the point is if you look I am using \compressFullBarRests which I
think defaults at 10 or 11, so if I wanted them to 'compress' at less I'd
need another line for an override.

Again I didn't know (like my MMR bug on 3/4 time I reported last year) if
this issue as to do with non-'simple' time sigs (er...like my MMR bug I
reported last year) and/or MMRs; and I couldn't evidently reproduce this
easily without understanding what was going on - which keith evidently
does having done a lot of spacing work - or without thinking it was MMR
related.

I don't know..it was what I had in my file it was the last line in my
\header block before the problem went away. It also had a ton of \markups
around it which I did remove also.

Well Keith did have a 'tiny example' but then started on about \markup
which I didn't have in my example (there are no \markup) and yes I NOW
know what he meant by \markup but that wasn't clear to me. So there were
two examples in my email. Had I known what I know now then I wouldn't have
bothered trying to contradict Keith and used his example, but how was I to
know? For all I knew \header {} was something 'special' something
'different' and might have been key.

My problem seems to have been 'guessing' what might have caused the
problem I.e MMRs, keith said no gave me an example that I didn't see was
the same thing and so I just gave mine.

That was all.
