I use eventListeners instead of onSelect onUnselect.

>>> Code for the popup:

	var highlightCtrl = new OpenLayers.Control.SelectFeature([vlayer,
clayer], {
		hover: true,
		highlightOnly: true,
		multiple: true,
		geometryTypes: ["OpenLayers.Geometry.LineString"],
		renderIntent: "temporary",
		eventListeners:
		{
			featurehighlighted: function(f)
			{
				popup = new OpenLayers.Popup("mylayer",
f.feature.geometry.getBounds().getCenterLonLat(),
null,
'some html text',
null,
true);
 				popup.autoSize=true;
// 				popup.panMapIfOutOfView=true;
				f.feature.popup = popup;
				map.addPopup(popup);
			},
			featureunhighlighted: function(f)
			{
            	map.removePopup(f.feature.popup);
            	f.feature.popup.destroy();
            	f.feature.popup = null;

			}
		}	
	});

	map.addControl(highlightCtrl);

	highlightCtrl.activate();

(popup is a global variable)
