I meet with the same problems,but as I try a little further,I find some stranges
I use IE8 with http://www.fusioncharts.com/gallery/Category.asp?Column3D
It can render the fusion charts normally
but when I open the local html files, the IE8 will report the javascript error
IE7 and IE8 in compatible mode both work fine
so I want to somebody can give me some advices
Thanks very much
