I encountered this just today. It happens in the latest V3 API when you try to create a marker with a an undefined latitude or longitude. On Firefox, it crashed my script altogether. My fix was:
function createMarker(m) { if (m.LATDD != undefined && m.LONGDD != undefined) { // if stmnt added to avoid odd IE bug var marker = new google.maps.Marker({ position: new google.maps.LatLng(m.LATDD,m.LONGDD), map: map, title:m.MAP_LABEL }); } } -- You received this message because you are subscribed to the Google Groups "Google Maps JavaScript API v3" group.
