I've been using \sectionmark to avoid long section headers running off the page (in Book style), but I've found that for some reason it only works the first two times out of three. Either I'm doing something really stupid, or something really strange is going on. I can send the file if needed (I haven't attached it this time, as it's big).
Any help appreciated .... Robin -- "There are only 10 types of people in the world. Those who understand binary and those who don't" - thinkgeek.com Robin Turner IDMYO Bilkent Üniversitesi Ankara 06533 http://www.bilkent.edu.tr/~robin
