Cannot change notes in address book.
Lately I cannot change the information of the "Notes" field in address Book. If I erase, or add, or change anything in notes and after few seconds it reverts to the original one. I tried to restart, turn off WiFi, repair permissions to no avail. It seems like some program that re-writes the information previously stored. Any help ?
