Hi Edward - I apologize if I'm not understanding your question clearly, but I think I know what you're describing. Are you referring to the outline of a comment that indicates the location on the page where the comment originates? That can be blue, but could also be any other color you wish. You may be able to make changes that improve your review by adjusting the settings in the Comments preferences (shown here). You may find increasing the size of your comments make for easier reading, and be sure to check the options in the Pop-Up Open Behavior. How the comments display and what you can see on screen is dependent on the magnification, of course. You say your comment locations are hard to read at anything lower than 1200% magnification. What are the dimensions of the document you're viewing? Another feature you might want to experiment with is the type of comment you're using. If you use a text frame with an arrow, for example, you can set the width of the line thicker, which is easier to see on screen. donna.
