In a ClarisWorks 2.0 Drawing document, you can select "Edit Master Page" from the Options menu to create objects that will show on every slide in a Slide Show.
Objects created while editing the Master Page of a drawing document are not saved when the document is saved as a PICT file.
A workaround is to choose "Edit Master Page" (Options menu), then "Select All" and "Copy" (Edit menu). Then deselect "Edit Master Page" and use the "Paste" and "Move To Back" commands on each page of the document before using the "Save As..." command.
