[wp-hackers] Facebook Like button will not refresh

[RePost]

I've implemented the Facebook Like button on a WordPress blog (latest version) and it is posting recommended links to Facebook. However, it's not refreshing dynamically. I must refresh the browser and reload the site to see the updated Like count. Otherwise, when I press the button, it just grays out. Here's the code:

<iframe src="http://www.facebook.com/plugins/like.php?href=<?php echo urlencode(get_permalink($post->ID)); ?>&amp;layout=button_count&amp;show_faces=false&amp;width=450&amp;action=recommend&amp;font=verdana&amp;colorscheme=light&amp;height=21" scrolling="no" frameborder="0" style="border:none; overflow:hidden;
width:450px; height:21px;" allowTransparency="true"></iframe>

And the site:

I'd appreciate any suggestions!
