Interesting combination of problems with the Googles Maps API when parsing the markers with XML
I’m seeing deadzones, everything within is unclickable, including the map itself.
InfoWindows won’t close clicking the close button (seem to be unclickable) or when clicking outside of the InfoWindows pane.
The Deadzone seems to disappear after the map is zoomed in, but the zoom distance isn’t consistent per location.
Heres the code if anyone can make or heads or tales of it.

Set
position:relativefor the div map_canvas. That will fix the overlay div problem.besides, it is not a zoomlevel problem. As you can see, your hand cursor disappears when you go over a part in the right hand side of the map.
EDIT: I tested your code myself, and the deadzone disappears once you set all position attributes to relative.
