    By the way,
    Simone,
    I tryed to use your off line modelling program to reconstruct the 3D
    constellation of the Niwaka and the ISS.
    >From here: http://www.satflare.com/download.php?sid=1 can download this
    version:
    VisualSatFlareTracker3D_173.zip
    If I start (on linux with wine emulator) it send only a run time error:
    "Runtime error 380
    Invalid property value"
    have you any key for me, where can I find the right path to the stars?
    t.janos
