I had this problem and because of it did a completely clean install of WordPress 3.2.1 and slowly added one plug-in at a time until I hit the problem again. Actually, this was only the second plug-in I added when I hit it. In my old configuration I went and disabled this plug-in and sure enough it started working again. Basically the Status, Visibility and Published On links don't work when this plug-in is installed. Oddly it seems to affect onto the Posts admin page and not the Pages admin page.
