Confirmed. I cannot see anything wrong with your MapType definition. Probably you discovered a bug in api. Please file it. http://code.google.com/p/gmaps-api-issues/issues/entry?template=Maps%20API%20v3%20-%20Bug
Nothing to do with the issue, but. You should delete the trailing commas in mapOptions object that IE users can access the page also. -- You received this message because you are subscribed to the Google Groups "Google Maps JavaScript API v3" group.
