I never had a problem before, but recently when my mac sleeps and I return to Traktor the history is gone. Neither is their a saved archive.
Its not a problem if I shut Traktor down, but now history evaporates on sleep!!
Maybe it is related to the sleep mode settings?
Found this on a quick search "Mac data loss during sleep"

Thanks for the article. I have checked my mac and it set to hibernate 3, which is safe mode, so it should save the data.
It used to save the data before I updated to the last version of Traktor Pro 3.
