Hi David,
Thanks. Pretty much the same situation here. I was hoping I could change a margin on the fly - I believe this can be done in TeX. But I iwll ahve to have a separate book/bookpart/whatever and stitch the score together. This is simple to do but very inconvenient when I am making lots of drafts and sending them to the composer for checking, approval, and viewing constantly.
Your idea is appreciated.
Andrew
