When I visit your site in IE 8 I'm able to see the problem. It is a bug and I will fix it for the next release.
Its caused by the apostrophy in O'Reilly, when I view the source of the page I see this on the line where it says the error happens:
showOdiogoReadNowButton ('319043', 'O'Reilly is Just The Messenger', '1', 290, 55);
I need to add code to escape that single quote/apostrophy. In the mean time a workaround is to remove the apostrophy from the post title.
