Although details are still appearing, Sophos is reporting that a particular combination of circumstances can result in FileVault passwords being exposed in plain-text log files. The combination is somewhat unlikely — the Mac had to be using FileVault 1 under Mac OS X 10.6 Snow Leopard, be upgraded to 10.7 Lion, and then updated to 10.7.3, all without switching to FileVault 2.

Track Changes Dates Reset on Save As in Word 2008
If you regularly use the Save As feature to create new drafts while working in Word 2008, you might notice that with Track Changes enabled, previously time-stamped comments and edits have their times reset to the Save As date and time. Work around this by sticking with your original file, but using Save As (or just File > Duplicate in the Finder) to make backup copies.
