[vtkusers] Mouse button release is still broken in 5.8.0 !

[Clinton Stimpson]

For some VTK users, this comes up often when adding an observer to the 
interactor style.  The interactor style calls vtkObject::SetFocus() so only it 
gets the mouse release event, and other observers don't.  One workaround is to 
add the observer to the interactor instead of the interactor style.  Perhaps 
another way is to modify the event focus.

Perhaps this is your problem.
