I am experiencing the same problem.
For many months I was using fusioncharts embedded in a SharePoint page web part. Everything worked fine. We updated both SharePoint and Adobe Flash was upgraded around about the same time and the charts stopped displaying. If I open the chart in a page of its own (i.e. not embedded in a SharePoint page web part) everything displays properly.
I am speculating that the newer version of Adobe Flash is causing the problem as I have viewed the page on older systems that have not been updated and everything seems to be working correctly with the chart displaying as part of the SharePoint page.
Any ideas on how to make this work would be very much appreciated.
Thanks!
