in the /webassist/google_javascript/wagmp_map_1.php file, find the following 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);
}
and comment the infowindow.open(map1,marker); line:
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);
}
