i experience the same problem too..usually i just use monitor color spoof (Ctrl + Y) to "solve" the problem but it's not by any way a solution to the problem..
guess when u want the pic to look like ur non-profile under cs2,
go to edit, color settings,
then under color management policies,
select off for the rgb tab.
hope this help.
but i think if u like to pp,
then u should not alter this.
