Rather than supertitles, subtitles, sub-subtitles, etc. why not have something like a header for the page which can be configured differently for the first page and subsequent pages (possible even odd and even pages!)? Basically, similar to the tools available within word processors.
This would grant full flexibility to users and even allow, for example, the inclusion of hymn numbers. At present I have to import into Word or Publisher to achieve this.
I have had the same problem pasting and inserting into Publisher 2000 (i.e. lost of separate lines making stems and beams and general wierness with ties and slurs). However, all works fine using Publisher 2003, so I guess MS have sorted out their EMF file reading.
It's a pity as I generally find Publisher 2000 easier to work with!
