If one closes the default micro-blogging stream window when connecting to Libervia, it is then impossible to open up new conversations with contacts. How-to reproduce: -Login to Libervia -Close the micro-blogging stream (upper right-hand corner) -Drag a contact name to the middle of the screen(!) ... Nothing ! Edit: This isn't really a blocker nor a bug in that one currently has to drag names to the top of the windows area. Suggestion: When there are no more windows, dragging to the _middle_ of the area (not only the top) should create a new one there.
