In the Preferences under the Commenting section there is a check box called Always use Log-in Name for Author name. It is checked by default. If that check box in not checked what is supposed to be used for the Author name?
My first thought is that the name I enter in the Identity section of Preferences would be used.
From Acrobat's help:
"Always Use Log-in Name For Author Name Determines which name appears in the pop-up note you create. If this option is selected, the Login Name in the Identity panel of the Preferences dialog box is used. If this option isn’t selected, the default name you specify for Author in a comment properties dialog box is used. Selected by default."
