POETFREAK I tried this and the first thing I notice is "BETA" in the title, but it worked fine for me. I created a new diary, added a new entry, saved, quit reloaded it and reread what I had entered. Even entered a second entry under today, then discarded it. The password feature was a nice touch but I did not check out how secure the file is, but it did not blow up on my PowerPC OSX 10.4 iBook.
