I had some problems and after a whole day of troubleshooting discovered that CS4 uses the monitor profile for the primary monitor regardless of what profile is selected by the OS for the second monitor (at least this is what happens on Mac). If I set the primary monitor's profile to match the second monitor (and work on second monitor) then this issue is resolved. Adobe should fix this ASAP. I think I will start new thread about it. This is a subtle problem but can ruin all the work done on a machine relying on a calibrated monitor and ICC profiles!

The profile for each monitor is used by Photoshop on the respective monitor. You need to calibrate and profile each monitor and use the resulting profile for each monitor.

That is absolutely the wrong thing to do. Calibrate and profile each monitor separately.

Adobe has nothing to "fix". Everyting is working as intended.
You need to learn about color management. Photoshop has used the monitor profile for many, many versions now.
Please read the whole thread before adding any more replies. This question was already answered. (Hint - turn off OpenGL acceleration).
Ramón, you jump to many conclusions without knowing anything. Not at all useful.
Both my monitors are independently calibrated using an i1 Display 2 and ColorEyes.
The colours on the second monitor are only right when the second monitor's profile is applied to the first monitor. I will try deselecting the OpenGL acceleration now.
My reply was based solely on your posted text (hardly a model of lucidity) not on "jumping to conclusions". Sorry I wasted your time and mine.
