Greetings all,don't understand why all of a sudden the scenery library rebuilds itself each time fs9 is started.I ran flight sim mgr 285 and it corrected some # sequences but i am baffled.Any help will be very appreciatedBest regardsAndrew

Andrew,One quick first test.Start FS and go to scenery ...Uncheck all your installed scenery and addon scenery.Exit FS.now test again ... if ok, then start "rechecking" each scenery til you find the problem.

Also right click your scenery.cfg file and choose Properties. Make sure it's not Read Only.Hope this helps,

Thanks its kbos and there was a double entry in the scenery cfg. I deleted it and ran flm285 again and all seems to be well in the world again.Best regardsAndrew

Andrew,Ok,Glad you found the cause.Have a good flight!
