Yeah, that is strange. It looks like they are using numbered lists for the options rather than explicitly defining them as 0 and 1. For some reason Netscape is ignoring the start="0" attribute in the <ol> flag. Maybe it is not standard.
My guess is that the numbered lists were put there by the editing program. Just like how MSWord thinks it can predict what I want to do, and starts to number lists for me. AutoFormat in most cases, is useless.
