IE 8 displays my "edit posts" page funky – any ideas?

I use quite a few wpmu premium plugins and I was wondering if anyone else has run into the following issue. I just updated from WPMU 2.6.5 to WPMU 2.7.1 and I cannot figure out why IE 8 is displaying my "edit posts" page in a really funky way. It does not do this for the "edit pages" page. Here is a screen recording of what it looks like? Does anyone have any ideas why it would do this?

Thanks in advance!
