Thanks for various responses, but am getting even more confused.
This is what happened today:
1.Opened FSX and STB, set at EGKK at 07.20 LT. All OK. After about 2 minutes, either UT2 and/or STB "re-set" and about 50% of the flights
listed with departure times after 07.30 vanished from the STB "departures board".
2. Selected an Easyjet departure to MIlan which was taxiing out via "View AI", and followed it w/o problems, until approx. mid-channel and
passing FL305 for FL330 my PC crashed completely [ again, just like yesterday ].
Is that the way it is meant to work ?
