In lib/tpl/*/design.css files muss noch die width: der button box angepasst werden.

Alter code Schnipsel:

div.dokuwiki div#size__ctl {
    float:right;
    width:60px;
    height:2.7em;
}

Neuer code Schnipsel:

div.dokuwiki div#size__ctl {
    float:right;
    width:80px;
    height:2.7em;
}

Follgend eingebundenes Bild muss noch nach lib/images/reset.gif kopiert werden.
