Replaced TinyMCE 2.x with 3.0 beta 3. Supports everything but IE. Also rewrote the editor interface completely from the ground up.
.mcePageBreak {display:block;border:0;width:100%;height:12px;border-top:1px dotted #ccc;margin-top:15px;background:#fff url(../img/pagebreak.gif) no-repeat center top;}
