one more time.  DAMIEN, YOU ARE AWESOME.  after so many scratching head, googling, and wondering why MY photoshop didn't have that option...  It only needed you to take a look for a second.  Geez!

Also, while you're here -- make sure you're working in the correct color space.  You've got a setting wrong somewhere.  http://www.damiensymonds.net/art_tscs000.html
