java.lang.NullPointerException in com.steema.teechart.drawing.Graphics3D.pointInEllipse(Graphics3D.java:783) ~

We are getting NPEs. Sadly we are not able to reproduce them. Maybe someone with more insight can have a look at this?

Here the Full message:

Hello,

We'll run some tests, see if we can provoke the error.

Do you have any information about any circumstances that might help us get nearer to the setup of the original app? It's swt I see.

Thanks and regards,

Somehow the click event was triggered. But I have no idea how.

We created the following patch solving the problem for us.
