Invisible characters may disappear when text is right justified. Try this test:
1. Create a new Word Processing document in ClarisWorks or a new Report document in ClarisImpact.
2. Press the Return key
3. Turn on Show Invisibles from Preferences
4. Press the up arrow once to move the cursor to the first line
5. Click the Right Justify icon in the menu bar
Notice that the invisible representing the Return has disappeared but will reappear if Left Justification is chosen. This can happen with other types of invisible characters (such as a page break) if Right Justification is chosen.
