I upgraded to WP 2.0.4 the other day, and after that my lists (in the content field) doesn't look like lists anymore.
I've ruled out the possibility of it being the coding (tested the theme on a subdomain with WP 2.0.3)
Here is an example: http://comatose.nu/archives/
And here is my coding:
<ul><?php list_cats(FALSE, ' ', 'name'); ?></ul>
<ul><?php wp_get_archives('type=monthly&show_post_count=1'); ?></ul>
<ul><?php wp_get_archives('type=postbypost&limit=10'); ?></ul>
