Facebook Like Button - how to disable Comment pop up?

I'd like to disable the Comment box that pops up when a user clicks the Facebook (fbml) Like button I've placed on my site. Is this possible to do? I can't find any details in the documentation.

Simplest fix to hide the comment box after Facebook Like (XFBML version not the iframe one) is as given:

.fb_edge_widget_with_comment span.fb_edge_comment_widget iframe.fb_ltr {
    display: none !important;
}

Put the CSS style in any of your CSS file and see the magic, it works :)

Putting the iframe in a appropriately sized div with overflow set to hidden resolved this issue - although this is only actually hiding the problem as such.

I use this in my CSS:

.fb-like{
    height: 20px;
    overflow: hidden;
}

and render the Facebook button with the normal HTML5 code, something like this:

<div class="fb-like" data-layout="button_count" data-show-faces="false"></div>

gr-

What I did is crate a div for the "like" button like this:

<div class="fb_like">
  <fb:like href="yourlink" send="false" layout="button_count" width="90" show_faces="false" font="arial"></fb:like>
</div>

And this is the CSS :

.fb_like {  
  overflow: hidden;
  width: 90px;
}
