My home airport ie KLWB which has one runway (Longest in the state) thanks to the Greenbriar Resort and a mess of private and company aircraft. A short distance from the Rwy. 22 end Mr. Gates has a Navigation Facility Shack sitting in the middle of the runway in FS9.Strangly, the KLWB location (Eastern West Virginia) is in the "Western North America" Area/Title of the Fs9 Scenery.cfg. I added "Exclude=N37 51.79,W80 23.7,N37 51.8,W80 23.71,objects" in order to remove Mr. Gate's shack from the runway.Now the mystery: Periodically, something removes my exclude line. I suspect that it has something to do with revising American Data, USA Roads, or possibly FSW Clouds or some other similar program but am not sure of this at all. I guess it is probably relative to adding or modifying scenery in the library, but I have not edited or removed my exclude line. A totally new scenery.cfg is not being redrawn when this happens as all of my addon scenery is retained (Fly Tampa, SimFlyers, Manhattan etc.etc.) I can reenter my exclude line, but it has now disappeared three or four times in the last few weeks for unknown reasons.Only that exclude line is removed by a grimlin somewhere.Any ideas?Thanks:RTH

It is certainly possible some of the downloads are replacing your scenery.cfg. That is why I recommend not putting the excludes and flattens in that file. It is better to place a separate exclude or flatten in its own *.bgl.Download the attached zip file and place the *.bgl in your Addon SceneryScenery folder.W. Sieffert

Thank You Sir:Worked like a champ. I appreciate the tool and will try to remember this one.Respectfully:RTH
