Hi, I've got the exactly same problem. When forcing to render in Javascript sometimes the charts are hanging and just showing "Loding chart. Please wait." I'm using 4 charts on same page and it is randomley one of the four that doesn't show up. We have done tests with MACs, PCs, Chrome, Safari, Internet Explorer and can not tie the problem to a specific browser or environment. I could live with that FusionCharts automatically switch over to Javascript on devices without Flash, but when using Flash I can't print charts from Chrome.
Anybody else having this problem?
Regards, Erland
