I have tested the Code with Mono 2.4 Windows and 2.4 Ubuntu and 2.2 Windows on
a Laptop and I always get the same error, wether I drag a cardinal symptom or a
symptom. Sometimes it is possible to drag a node, but the drag_over event does
not work properly and the application crashes with the same error message on
drop. It is also possible to Drag Symptoms and cardinal Symptoms from the
symptoms window (Windows: symptoms). But though I have started the drag with a

tvSympt.DoDragDrop(mSelNode, DragDropEffects.Copy Or DragDropEffects.Move)

in the Drag_Over event: If e.Data.GetDataPresent(SourceNode.GetType) Then

the result is false!
