When a page has a small 9 with strikethrough, the result appears to be a strikethrough 0. this is very confusing at times. Ie: http://www.amazon.com/exec/obidos/tg/stores/detail/-/electronics/B00005AW1F/pictures/14/002-6728077-1940821#more-pictures

I think it's the code's fault, not K-Meleon's.
See here:

<style type="text/css"><!--
..........
.listprice { font-family: arial,verdana,helvetica,sans-serif; text-decoration: line-through; font-size: small; }..........
--></style>..........
<span class=listprice>$169.99</span>

The browser will use one of the fonts listed there (the first one being the first priority, as far as I know). I've tried Arial 10 pts and the strikethrough 9's sure look like strikethrough 0's.

Oops, sorry, there should be a [/b] tag after the second "listprice" to turn of the bold formating. :-P
This is to show that the "$169.99" is displayed using the "listprice" style, which uses the font Arial with strikethrough.
