padding-{vb:stylevar left}: 20px;
}
.postbitlegacy .postfoot .textcontrols a.quickreply:hover, .postbit .postfoot .textcontrols a.post_thanks_button:hover {
background: url({vb:stylevar imgdir_button}/post_thanks-hover.png) no-repeat transparent {vb:stylevar left};

blue code to replace with post_thanks_button

so, xml file ..

Will be fixed as part of supporting postbit_legacy in next version.
