Several Properties on one Map: How does the map view feature work?

Hi,
When I search properties on Ulisting Demo site using search listing window it gives out search results as a list. No problem here. But when I try to see them all on a map and click Map View after that - nothing happens. So is it the Map View feature not working properly or is it something else? Also, if I want to display all my Featured Properties on the map by default(not as a list) can I do that within the current installation of this module?

Thanks,
Mikalai
