In the map js file, find the following line:
// open info window for default address
if (isDefault) {
infowindow.open(map1,marker);
map1.setCenter(point);
}
and comment the infowindow.open line:
// open info window for default address
if (isDefault) {
//infowindow.open(map1,marker);
map1.setCenter(point);
}
NOTE: the map1 reference may have a different number
