'Share' pop-up only half displayed

Hi guys. Thanks for this plugin.

I’m using the ‘Facebook Like Button’ in the sidebar in a child theme of twentytwelve. The maximum width of this sidebar is ±26% (250px). I can change the width of the widget in the backend. But a soon as i hit the Like or Share button, only a half pop up shows. I didn’t add any modifications to the sidebar of the child-theme’s css, nor did i add changes to the css of the facebook plugin. I assume this pop up has a width of 450 px.

Does anyone know how i can get the full pop up? (Without having to change the width of my sidebar, ’cause i want it to stay 250px). If there’s no solution, I’d like to disable the pop-up. Idea’s, anyone?

I’m building my website on a local server so i can’t paste a link. Here’s a link to my screenshot: http://imageshack.com/a/img577/1978/2e8a.png

Anyway, thanks in advance :-), happy developing!
