  Does the maximize button actually work? I've tried texdoctk under
  sawfish and yes, there was a maximize button, but it didn't work.
  That's why I say not displaying some buttons is a good thing, if they
  can't be used.

  And the gnome-xbill app clearly states so. I *think* the applicable
  standard is <http://www.freedesktop.org/standards/wm-spec/>:

    Fixed size windows

     Windows can indicate that they are non-resizable by setting
     minheight = maxheight and minwidth = maxwidth in the ICCCM
     WM_NORMAL_HINTS property. The Window Manager MAY decorate such
     windows differently.

  I don't think clicking the maximize button in gnome-xbill would do a
  thing, but hey, maybe I'm misremembering.

  My understanding of the protocol involved is practically null, so I
  might be completely wrong. But I'm pretty sure of what I'm saying.

  It's a possibility. Really don't know when was this introduced. But
  xload seems a pretty old app and it manages not to get minimized ever.

  I definitely would appreciate some insight wrt this.
