[QUOTE="MacInWin, post: 1741338"] 1. Don't forcibly shutdown the Mac if at all possible. That is NOT good as it leaves many items in cache still active and the next boot picks up that cached stuff that may or may not apply. If you absolutely have to do a forcible shut down, then on the next boot, do a safe boot first, run DU to check the drive and then you can reboot normally. You should also anticipate that even after that routine you will see cache-related strangeness sometimes.
