I'm still using XP, but anyway I'm never using standard installation passes. Since my first PC Set-up I had always installed my programs on another (physical) hard-drive or at least in a separate partition. So this misbehaviour is new to me too. I have never noticed this before. I posted the detailed description what's going with the hope airnav noticing it and for others to sharpen their eyes whether they have the same issue or not.
I think I'll take the next database update, because between the last and now I have posted to many new Airframes which were already added and have auto-pulated or have populated by population function of MyLog explorer without any problem. The Saturdays have all populated without a problem, except the ICAO Ident issue, which is in my opinion an annoying, but more or less a minor bug.
Well, perhaps my PC/RB Software doesn't like this two airframes and has decided to refuse them? ;-)
