Zarzal,
I think you're getting me a little closer. I have not ever made any changes in the style editor, but your post helped me find where the stylesheet classes referred to by Rick could be found.
I went to the style editor and opened up Post Properties. When I choose .post-buttons, an empty box opens up underneath. I'm sure I'm missing something basic, but I have read and re-read Rick's post and still can't figure out what I do to fix the buttons.
