    Hi Janos,
    
    please check whether the following fonts are installed: font couri.ttf and 
    pala.ttf
    I did not check the latest version on Linux, but one of the problems may be 
    connected with the fonts.

    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?

    According to the current TLEs and data, on the 12th of December at around 21
    UTC,
    the FitSat-1 cube sat will overtake the International Space Station, exposing
    its LEDs
    toward the station.
    
    Thanks to both the good orientation and the short distance between the two
    objects,
    the LEDs should be easily visible from the ISS.
    
    However, the first LED activation after this date is scheduled only at 22.10
    UTC
    December 13 when the Station will be already too far.
    
    13/12/2012  22.12.30 UTC - Distance 2330 km - Led Angle 55 deg - LED Magnitude
    11
    
    If the activation would be rescheduled for the pass at 23.06 UTC on the 12th
    of December
    (one day before) the same regions on the Earth could observe the LEDs (the
    pass is very
    similar to the planned one) and the ISS would be in a good position as well,
    at a distance of
    260 km under an angle of 57 deg. The expected magnitude would be of 6.
    
    12/12/2012 23.06.00 UTC - Distance 260 km - Led Angle 57 deg - LED Magnitude
    6.3
    
    Best Regards,
    Simone
