I have a weired issue and no idea how to address it. I use a block view on my front page that displays a gmap. When the page loads the map is displayed correctely. When I zoom in or out the map doesn't load (sometimes it loads one or two levels, sometimes no level). The weired thing is, when I use the exposed filter for that view and the gmap loads again (using Ajax), the zooming works just fine. So it seems that when the map is getting loaded again it works but not if the page gets refreshed.
The site I'm talking about is www.my-business-location.com.
BTW: Other gmaps that I use with the gmap field module work well.
Does somebody have an idea what causes this behaviour or how I could find the mistake?
