comment the code that loads the info window.
To keep if from opening on initial load, do search for all occurance of:
marker_0_0.openInfoWindowHtml
It will be in a few places,Whether to comment it or not depends on the surrounding code. It will either look like:
if('address_0_0' == 'address_0_0')
marker_0_0.openInfoWindowHtml(address_0_0.infowindowtext);
or:
GEvent.addListener(marker_0_0, 'click', function() {
marker_0_0.openInfoWindowHtml(address_0_0.infowindowtext);
});
to make it not load the bubble on initial load, comment it if it looks like the first example:
//if('address_0_0' == 'address_0_0')
//marker_0_0.openInfoWindowHtml(address_0_0.infowindowtext);
This will still allow the bubble to load if the marker is clicked. if you do not want that to happen as well, comment the second example too:
//GEvent.addListener(marker_0_0, 'click', function() {
//marker_0_0.openInfoWindowHtml(address_0_0.infowindowtext);
//});
