I haven't managed to find out how to do "stuff like 4,4,4,8" - the number of bars per line in the leadsheet seems to accept only one value.

I've tried various values for this, and get correct positioning of the chords if the end-repeat mark comes at the end of a line - in the case of this song I have to choose either 2 or 17, as the end-repeat is at bar 34. Other values bring out the fault - with chords attached to bars beyond 34 appearing at various points above and below the correct place (and some where they should be).

Looking through my leadsheets, I've come across another example. In this case there is no tag, and the end-repeat mark comes at the end of bar 45. If I use a factor of 45 (3, 5, 9, 15) for bars/line, the chords in bars 46 onwards are correctly placed on the leadsheet, but any other number causes them to be displaced or missing altogether.

It looks as though the common factor in the faulty files is that the end-repeat mark doesn't come at the end of a line in the leadsheet.

I'll put together a bundle of files for support@pgmusic.com.
