Hi again,
Note that the GeoMap visualization, like all flash visualizations, can act
strangely (or not work at all) when run from a local html file (via
file:///) but work fine when run from a non-local server.
Try hosting your html somewhere and accessing this, and the events should
work fine.
Regards,
VizBoy.
