FB like button comment pop-up off screen

Question

My like button has fixed positioned near the edge of the screen. As a result, clicking "Like", the comment pop-up box is half-on-screen, half-off, making posting comments difficult.

Any ideas? See the problem on the following screenshot:

Interestingly, the Google Plus button does not have this problem.

I know this is an ancient post but for anyone else stumbling into it from google: the solution is to simply add a css class for .fb_iframe_widget and give it a negative top margin with !important.

For example:

.fb_iframe_widget{
    margin-top:-163px !important;
}
