Something to try.
Visit the Commenting category in Preferences.
Play with the configuration choices for the three panes (Viewing Comments, Pop-Up Open Behavior, and Making Comments).
There is nothing in the preferences >> commenting that can help.
Anyone else using commenting and experiencing or annoyed by this?
Anyone using comments a regular basis and finding the same or different?
I am thinking of asking our QA people to turn on their setting for "restore last view settings when reopening documents", and that may help. One of them is not too friendly so may to suffer this one out.
