Hi again.
Eli I hope you're reading this! =)
I'm getting really sporatic responses from a listener to the
ChartMouseEvent.MOUSE_OVER_DATA
Note it wasn't this way in the alpha. Only significant differences on
my part is the use of XMLListCollecitons as data providers.
see the sample app below.
Thanks,
Thunder
