IE 9 gives me fits on this site. I went to Chrome and it's all good.
IE states that there are security certificate errors with a block to select to show contents. It is a crap shoot when the block is selected. Sometimes the page loads, sometimes IE locks up. It has been this way since the latest MS update. This is the only site doing it. Good luck running it down.
EDIT, it is IE10 that is problematic, not IE9.
