// BUG: if this symbol is defined the problem consists on:
//      - main window is created.
//      - settings are saved (and applied), but in this case no toolbars exist yet, so they don't
//        apply to any toolbar.
//      - after 1 second the GUI is created.
//
//      How to reproduce ?
//          - Move one toolbar to other place (bottom, left, right, or deattach it).
//          - Close the test (so settings are saved).
//          - Reopen the test. The toolbar you moved is not keeping the place you specified.
