Hi Lars,

  gnus-thread-hide-killed is a variable defined in `gnus-sum.el'.
  Its value is t
  
  Documentation:
  *If non-nil, hide killed threads automatically.
  
  You can customize this variable.

So it is set.  In gnus-sum.el I see

  (defcustom gnus-thread-hide-killed t
    "*If non-nil, hide killed threads automatically."
    :group 'gnus-thread
    :type 'boolean)

That means I'm using the default setting.  Isn't that supported?

Thanks
  Detlev
