It's a map using clusters for markers, clusters work ok, markers place correctly but no matter what I do I don't seem to get the infoWindows to open. OnClick event for infowindows displays the alert I added (but now it's commented so it does not show). So the onclick funtion works I think? It just does not open the infowindow... Kinda lost here, any help? I've been fighting with this so long I can even consider giving some quid in return for a working solution! (via paypal or so).
