I am having a terrible problem with accessviolation exceptions. Mostly when
closing the application, but sometimes while the app is running. There is no
pattern to it, it is completely random. I have several classes that create mappers,
planes, polydata, and actors which are private class members so they stay
alive as long as the class instance is alive and the scene is getting rendered
exactly like I want. When the main form is closing I call a DestroyLayer
function on each layer object which sets all the vtk objects instances in the
class to null. When creating the actors I pass a reference to the renderer
so I can add the actor to the renderer. The stack trace usually points to the Finalize()
function for vtkPlane or vtkMapper when the exception occurs and the exception
occurs at the very end of the application life cycle ( after the call to Application.Run()
