When you create a New Issue, there is a pop-up list in the New Issue dialog box where you choose to show/hide the revision markers of previous issues, in the Help files see: Documentation > Revision Management > Managing Issues: Show or Hide Change Markers in This Issue.
Thanks David. That is helpful. I think I did this because some of the changes disappeared, but some did not. Can you think of a reason that some of them would not disappear and some would disappear? This is what is happening.
