When you save a placemarker, the best way to do it is to right-click the placemarker in the "Places" diectory in the left (don't use the File menu on the top as this may create the problem you described). Select "Save as" and give a unique name to it. The current view on the main screen is irrelevant to this.Originally Posted by brewer
Each overlay is saved as an individual kmz file, so one for the original and one for the new one you created. So when you re-opened the new kmz file it only contains the new overlay. You can save two overlays as one kmz files but you need to place them into one folder in the "Places" directory and save the folder as described above. To create a folder in "Places" right-click "My Places" and select New>Folder.Originally Posted by brewer
