Dear Clayton,

  I'm having a problem getting the workflow for "Using Color Settings
and Profiles" to coincide with CS2. Your article states: "In Photoshop
Version CS2 these settings are done differently. To set a specific
printer profile you must first choose "Let Photoshop Determine Colors"
in the "Color Handling" picklist, and then choose the desired profile
in the "Printer Profile" list.  To get the equivalent of "Same As
Source", where the back end is automatically the same as the front
end, select "No Color Management" in the "Color Handling" pick list. 
The Printer Profile list will be disabled."
  OK. I switch to letting PS determine colors. I then choose as
profile "20% dot gain".  However, when I switch back to 'No color
management', the 20% dot gain disappears, the printer profile switches
automatically to "Working RGB, Adobe RBG (1998)" It is grayed out and
cannot be changed.
  I am getting confused, I think. I also see no on-screen changes when
changing the dot-gain setting. The article states that I should see
changes.  Am I missing something obvious?
 I hope you can help.......
 Best,
  Ginny
