Wow, Dieter, that was fast! Thanks a lot!
I attach my scenery library and I think it is in order. RTTM-stuff (incl. Hollis) at the top, TF (both) below RTTM and Orbx-stuff below Tongass.
Edit: O.k. I see: I should reinstall Tongass. That is a lot to ask for in P3D.
Will see if I do it or live with the trees for the Moment...
Thanks again!
