[vtkusers] removeActor() causes error ("wglMakeCurrent failed...")

[Markus Ott]

I'm calling removeActor() from the JPanel class to which the vtkCanvas
is added. The actor even gets removed from the canvas but nevertheless
the error occurs. What do you mean by "occur in the EDT"? I'm not
starting any other threads manually.
