    properties: don't destroy advanced dialog on 'delete-event'
    
    Rather hide it. The dialog is designed to be toggled between visible/hidden.
    When Esc key was pressed or the dialog was closed through clicking top right
    corner 'x' icon, the dialog was destroyed and next clicking 'Advanced' button
    brought malformed empty window.
