Some visitors don't see the markers on map

[Mads Andersen]

I have just installed the ContentMap and think it's a great module, that I'm looking very much forward to use.
Unfortunately I have a problem;

When I visit the map, I can see all the markers no problem, but using my friends computer I see the map showing Italy and no markers. - we both use Mac OS X and Safari (I have only markers in Denmark).

What might cause this problem?

Hi Mads Andersen,
could you give me a link to your site to see what could be the problem?
