Those are also called Fat-40, either because their "head" is bigger than was usual before, or (and I like this version better) because the characters are a lot wider than before. My guess is that a previous user didn't like the wide characters and wanted the old aspect ratio back. -Olaf. -- ___ "Buying carbon credits is a bit like a serial killer paying someone else to \X/ have kids to make his activity cost neutral." -The BOFH falu.nl_at_rhialto
