I'm a little perplexed about this problem. Yesterday I was at a friend's place editing a couple of images in PSCS2. I had to go out for a while, so I shut down the computer. After about an hour, I returned and tried to continue from where I had left off. Surprise: under File>File Info, there was no item on the left hand panel for History. I checked Preferences, and sure enough, under General, the History Log radio button was checked >Both, Detailed. I went back to File Info and in Advanced, saw that the history log had indeed been saved as metadata. I opened the history log text file, saw what exactly I had done, and finished editing.
So what is the mystery of the Missing History? And how to get it back?
Thanks,
Kumar
