 setOpacity won't work on a vector layer, if the vector layer is with other
 vector layers in a SelectFeature-Control (the SelectFeature-Control has
 than a Vect.rootContainer). With the following it will work:

 {{{
 OpenLayers.Layer.Vector.prototype.setOpacity = function(opacity) {
         if (opacity != this.opacity) {
                 this.opacity = opacity;
                 var element = this.renderer.root;
                 OpenLayers.Util.modifyDOMElement(element, null, null,
 null, null,
                                 null, null, opacity);
                 if (this.map != null) {
                         this.map.events.triggerEvent("changelayer", {
                                 layer : this,
                                 property : "opacity"
                         });
                 }
         }
 };
 }}}
