You may have saved your picture in a flat file format such as GIF or BMP. When you save your picture as a flat file, PhotoDraw discards any objects that lie outside the picture area and saves all objects within the picture area as a single combined object.
If you want to save all objects in the scratch and picture areas, you should save a copy of your picture in PhotoDraw MIX file format. The MIX format also retains individual objects in the workspace so that you can modify them after you reopen your file.
