[Zope] logged_out from CookieCrumbler

[Dennis Allison]

One of my sites uses frames.  User management uses the CookieCrumbler.  When 
a user logs out, a logged_out dtml-method is invoked.  The logged_out method
kills off session and browser information and then transfers to the initial 
splash screen which links to the login page which includes the login page in 
the frameset.  When the user logs out, the splash screen is rendered in one
of the frames of the frameset rather than replacing the frameset.  What's the 
magic needed?
