are you PC or mac? this might be a stupid question, but why does your CS3 need to know about your monitor profile? in color set-up you have to choose the profile for your workspace, which should be aobe RGB or RGBpro, but not your monitor profile....all other settings are really for soft proofing......this is on a mac.....
maybe i am wrong...i have a certain color "path" set up and don't stray...as long as it works i don't mess with it....
