IE8 Like Button

I'm having trouble reproducing the problem but on one of my coworker's computers and one of our users has reported an issue when liking one of our blog posts.


In a version of IE (i think IE8), when they try to like something and are not already logged into facebook, it prompts them to log in in a large window, but the log in is never successful and sometimes to pop-up doesn't disappear

Here's the error my coworker gets
