About location map

Dear all,
I'm using location and gmap modules to build a view to view all geotagged posts in this site:
http://www.fantapalermo.it/mappa

I'm very happy with these and impressed, but I'm not able to do a simple thing.
I have a block below each geotagged post, using this macro:
[gmap |width=100% |height=400px |control=Small |behavior=+autozoom +notype | type=Hybrid]

You can see in action here:

If you see the map you can see the point. If you click on it you see an empty cloud. I would like to have no cloud, but I do not how to set this behavior using a gmap macro.

I have just set in admin/settings/gmap_location "Marker action: Do nothing", but I have always this empty cloud.

Do you have an idea to solve it?

Thank you,

Andrea
