Hi Folk
Can you please have a look at http://www.friars.co.nz/map.php and let
me know if the map is working on IE6 (just do a simple search).
Unfortunately, I do not have IE6 anymore and so I can not test it.
I think there maybe some trouble with retrieving the AJAX xml. Below
is the code for this:
var i = new Array();
var j = 0;
var jmax = 4;
var http_request = false;
Thanks a million
Nicolaas
