I got same problem at my fb-blog.net. But I was solved. I do this :
– Clear my application cache with CCleaner (googling and free download) because i used Win7. You can try skip this if you not win os
– You MAY need to delete the wp-includes and wp-admin folders and copy them up again fresh from your WP 3.2 manual download.
– Clear my browser cache and everything.
Voila.. my problem solved and good run with WP 3.2
