I created a chart with the following javascript:

<script language="javascript" type="text/javascript">
var piechart_typeReferer = new FusionCharts("/charts/v3/pie3d.swf", "mychartId_typeReferer", "100%", "160", "0", "0");
piechart_typeReferer.addParam("wmode", "transparent");
piechart_typeReferer.setDataXML("<graph><set value='10'/><set value='10'/></graph>"); 
piechart_typeReferer.render('typeReferer_chart');
</script>

Is this normal behaviour, and if so, how can i avoid it?

Thanks in advance.

The "you'll need to click outside the pie chart once and then scroll" method only works when you're using the <object> tag, But when I use the javascript approach, clicking outside the chart doesn't make any difference. And i really want to use the javascript method

Is there a work arround, or maybe in an update, you could add an extra tag called "disableMouseEvents" or something like that? Just thinking out loud..

piechart.addParam("wmode", "transparent");

If this parameter is set, any mouseover on the flashchart will capture all mouse event, without clicking first.
I think a solution like i've posted before could be a way to tackle this problem.
