    Bug 694892 - Windows [X] from drawing window leaves zombie
    
    With preference "Keep toolbox on top of diagram windows" the toolbox
    followed closing of the diagram window. This was due to still being
    transient. We have to break the connection between both windows
    otherwise the toolbox will go but the application wont exit.
