Hello, I'd like to do something similar to the FusionMaps GUI (http://www.fusioncharts.com/maps/Demos/GUI/Index.html) with regard to dynamically adding markers to a FusionMap. My question is: how do I capture mouse clicks on the map? I know the FusionMaps GUI must be doing it but I can't figure out how. I'd like to be able to do this in JavaScript (as opposed to customizing the map source or creating a wrapper movie). Any help would be greatly appreciated! Many thanks!!
