All right then, allow me the Next n00b Question:
How do I load this Google Maps API script with GUnload in it? I have
this Maps recipe from a book and just applied it exactly as it was in
the book (you know, great programmers don't write code but re-use it).
Turns out the recipe is incomplete.

Yes, but when the thread executes the window.onload setting it IS
being asked to execute initialize() - why doesn't it do that?
I have Googled it and found this:
google.load("maps", "2",{"other_params":"sensor=true"});
function initialize() {
var map = new google.maps.Map2(document.getElementById("map"));
map.setCenter(new google.maps.LatLng(37.4419, -122.1419), 13);
}
google.setOnLoadCallback(initialize);
Is this how it's supposed to happen?
