[vtkusers] Iren->AddObserver( vtkCommand::KeyPressEvent, CallbackCommand );

[Louis Desjardins]

Hi there,

Why is it then when I have:

Iren->AddObserver( vtkCommand::KeyPressEvent, CallbackCommand );

then when I press a character, the callback function happens 3 times, and 
when I press Enter, or space bar, or Alt etc.. , then the callback gets 
called 2 times..

Why isn't the callback happening just once???
