. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . Note: fixed; files that can't be accessed are no longer in the backup
In both my XP Pro and Vista systems, the above exposure seems to be fixed. Every file that was not in the backup had a "Failed to access" message.
The Vista test uncovered a small bug. A few files that were backed up and removed also had a "Failed to access" message.
So this is a false message bug (relatively harmless).
