As I said though it seems odd that only mutt suffers from the problem (on my xubuntu systems anyway). Presumably both 'less' and my editor 'vile' use ncurses too and they just wrap long lines if you tell them to do so. I'll have a talk with Tom Dickey who is the maintainer of both vile and ncurses, he may be able to throw some light on this. -- Chris Green
