Never since I got this plugin (SexyBookmarks) this option have worked.
But now it cause me some frustration to see that I actually want those buttons.
In the option panel, you can customize the bottom bar, ok, but also there is the option to add this 3 other buttons (plus facebook's send button) and they have the option to be buttons, standard links or boxes-style. If I choose the latter, just 1 is showing as a box (facebook one, but sometimes it varies), the other 2 are showing as buttons, and I can't figure out an answer for this.
I tried deleting chache files or browser and on the site, nothing works.
