I think this is a bug. To recreate:
- Load http://dbsgeo.com/latlon/
- Enter "2nd Ave. & 5th St., Brooklyn" into the place name box and click "zoom to place"
- Result -- map moves to the location and info is displayed below map.
- Enter "39th St. & 3rd Ave., Brooklyn"
- Result -- map moves to the new location but the info below the map doesn't change.
