It seems that I am unable to add a "key" parameter to the Parameters property on a GoogleOverlay. I am watching Fiddler as the requests go out to Google Maps servers (free version, just giving it a whirl), but they do not include the 'key' property, which seems to be now required to use the Static Maps API (as seen here developers.google.com/maps/documentation/staticmaps/#api_key). I am using the Daily Production build 126.96.36.199. Can you suggest a way to add this parameter to the request? Thanks very much!
