How to remove an automatic click event on google map overlay?

Question

Hi,

Can anyone help me to remove click event from the kml polygon? When I click on any part of polygon, window message pops up with a data KML TEST which is from KML file. I just want to have polygon drawn over google map without having any click events. Does anyone know how to achieve this?

This is my page: http://www.keithwoodrow.co.uk/globalmap-nav/

This is how my KML file looks:
