Paper column extents usually are not what you want if there are multiple staves, since it's the union of things in all staves . Also, grobs that align on parents should usually have something more specific as X-parent (eg. a notehead). -- Han-Wen Nienhuys - han...@xs4all.nl - http://www.xs4all.nl/~hanwen _______________________________________________ lilypond-devel mailing list lilypond-devel@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-devel
