Hi Angshu,
We are seeing this problem as well. Here are the steps to reproduce (due to the nature of the bug, a screenshot is not much use here.)
Go to http://www.fusioncharts.com/demos/business/management-dashboard/view/
Move your mouse over one of the Column charts SWF and then use the mouse wheel to scroll the page up/down. Notice the page scroll.
Move your mouse over the Pie chart SWF and try the same. Notice the page does not scroll.
Expected result: The SWFs should sink mouse events in a consistent manner, preferably, not at all.
Using Mac OSX, Chrome 17.0 and Flash 11.1
Thanks,
- Randy
