Like window – strange size

Hi,

i have just installed add link to facebook on my page.

When i like an arcticle there should be a small window with the status. But this window does only appear in a strange way: http://abload.de/image.php?img=capture76l86.jpg

How can i solve this?

Thanks for your help!

Regards

Marko
