ok,I tried out your example.Here is what I think you are not doing it
right.You are loosing the reference to polygon object.I copy page
chucks of the code I changed to make it work
1] Created a global variable for polygon.
var map = null;
var polygon;
2] You already have global variable for map object so I removed var
if (GBrowserIsCompatible()) {
var map = new GMap2(document.getElementById("map"));
to
if (GBrowserIsCompatible()) {
map = new GMap2(document.getElementById("map"));
3] important changes.reused polygon global variable for both click and
dragend listeners( removed var , and renamed newpolygon to polygon)
polygon = new GPolygon([
new GLatLng(document.getElementById
('latstart').value,document.getElementById('longstart').value),
new GLatLng(document.getElementById
('latend').value,document.getElementById('longstart').value),
new GLatLng(document.getElementById
('latend').value,document.getElementById('longend').value),
new GLatLng(document.getElementById
('latstart').value,document.getElementById('longend').value),
new GLatLng(document.getElementById
('latstart').value,document.getElementById('longstart').value),
], "#CC0000", 1, 0.8, "#CCCC00", 0.1 );
map.addOverlay(polygon);
have fun
