Re: [Pharo-dev] Nautilus strange pattern

      We should make sure to unregister to all announcement when the window is
closed.
(Or is there any reason or situation in which nautilus can properly work
after the window is closed?)

Hi
I'm trying to understand what there is a need for this window ifNil: [^
self ]
And I wonder is this is not  problem due to a global announcer that would
keep announcer even when the nautilus widget
has been deleted.
Any other suggestions?
