ReproducibleScript:
Using 'iconwindow' to create and manage an icon results (by design,
    according to the code) in the
    button events being disabled.  Therefore, when a user clicks on the icon
    to map the application, the
    button event is handled by the window manager, as if the icon isn't
    there.
    
    This results in un-uniform behavior for the icon.  Every other icon on
    the desktop will map when
    clicked, except for the tk application using 'iconwindow'.  In fact, if
    the 'twm' window manager is used,
    the application cannot be mapped without the use of 'twm's iconmanager.
    
    In the file tkUnixWm.c, there's this comment:
    
    * Remove the icon window relationship.  In principle we
    * should also re-enable button events for the window, but
    * this doesn't work in general because the window manager
    * is probably selecting on them (we'll get an error if
    * we try to re-enable the events).  So, just leave the
    * icon window event-challenged;  the user will have to
    * recreate it if they want button events.

DesiredBehavior:
All icons should handle button events in the same way, regardless of
    whether the iconwindow function
    is used or not.  Uniform behavior of the desktop should be the design
    requirement.

Message:
Icon windows are a very little used part of X, and consequently are little tested in the various window managers too.  Alas.
