PSS B777 Beacons

Hi there!

I have got a problem nobody was able to solve or gimme a hint how to
solve it by myself until now, even not PSS or Justflight (well, both
of them didn't answer my request within the last 8 weeks). I am a user
of PSS B777 Professional addon. By now I find that it is a real well
done simulated addon, but there is something I don't like. The beacons
of this aircraft are blinking when in use instead of flashing like the
real one does. Does anyone know if there is a possibility of making
them flash? I would appreciate any help. Thanks so far.

Eric
