Using Vista.After adding a new addon scenery, and going through the procedure to add it to FS9, I checked SCENERY.CFG to discover that the new entry has not been added in to the file. The new scenery works fine, but I'm trying to add an exclusion entry to get rid of some unwanted trees/bushes, but there is no entry for this new addon or any recent addons as well.Quite happy editing the file, but a manual entry into the file doesn't appear to work.Please help..:-hmmm
