Dragging causes pie slices to disappear in IE7 about highcharts

[TorsteinHonsi]

In another demo, areas also disappear: http://www.jsfiddle.net/9du5y/

Is there possibly any progress made on this issue? The only (inefficient) way I've found to work around it is to redraw the chart on cancel.

Can't see how we can fix this... It is obviously connected to some layout bug in IE. I tried appending a dummy rectangale to the container after move, which helps in some cases of IE layout bugs. For now I think your workaround is the best solution.

Still valid in 3.0.2

Still valid in 5.0.7 when dragging by pie slices

The problem appears only in case the third party sortable widget is used. It's possible to resolve the issue through calling chart / series update that will force redraw the shapes.

  $('#sortable').sortable({
    stop: function() {
        pieChart.update({
            series: [{}]
        });
    }
  });

This seems to be a more a technical support case than a bug.
Closing as possible to be resolved with provided code, but this issue could be reopened if you have more comments and info about the problem.
