have a question that i hope you can help me with--that wort of follows this thread--. i'm using PSCS4 and i'm trying to delete the "history" portion that was originally saved in my XMP data. i've gone to the "file info"->"advanced" window pane (tab) and deleted the "history" folder (like you suggested in your article a photoshop history lesson"), but the folder continues to reappear with all the initial history data. it appears like i delete the history folder, but then when opening up the "file info" window again, all the history is there like it was before i attempted to delete it.
can you help me out?
best-- and many thanks.
