in the isdefault code:
if (isDefault) {
//infowindow.open(map1,marker);
setTimeout("google.maps.event.trigger(wagmp_map_1_obj.markers[" + wagmp_map_1_obj.markers.length + "], 'click')",1000);
//map1.setCenter(point);
}
you have the line to force the click, which opens the info window, change that to:
if (isDefault) {
//infowindow.open(map1,marker);
// setTimeout("google.maps.event.trigger(wagmp_map_1_obj.markers[" + wagmp_map_1_obj.markers.length + "], 'click')",1000);
//map1.setCenter(point);
}
