Issues with Mailing List Archives

I don't think it is just me, mainly because I've tried IE and Mozilla, but the Mailing List Archives (http://framework.zend.com/archives) have issues. This seems to have corresponded with the new look of the site. The problems seem to be on the main page and mainly occur when I hit the back button in my browser. I will either get no listed messages or about 1/3 of the list. But this morning, coming fresh to the site I was getting no listed messages.

Any ideas?
