admin style problem

very strange. for some reason the stylesheet from my active theme is partially affecting *some* (but not all) of the admin pages. i’ve reinstalled wp-admin and wp-includes to no avail. in particular, the manage and edit pages pages are messed up. other admin pages are fine. any ideas?

for context, i installed this site using Fantastico (godaddy is the host) and then updated from 2.7 to 2.7.1.

thanks!
