Financial Extension error. "Object reference not set to an instance of an object"

[Henrik]

I have been adding a financial extension to my fxchart.

I chose the from the Gallary "Analytical" the "Close prise and volume" chart.

 Then i start changing the chart via "Configure Axes and Panes" in the "Chart Tasks" menu.

The only thing I do changes is under "Y Axis Configuration" where I changes the chart from a "Multiple Panes" to a chart with "Primary and Secondary Y Axes".

When I press on the accept button I get the error "Object reference not set to an instance of an object"
