Using in computer overlay is ok for composition and general layout and workflow preview, but to do stuff like color correcting and matching you need to use a external video display, using a video output like a BlackMagic intensity or a Matrox MX02mini and a tv monitor that can take a decent calibration, and has full resolution, you can get 1080P in 22″ and up.
[Aaron O’Neil]“I’m not sure it could be called a video problem”
video as in computer display video, CS3 is not the latest set of apps on the block and sometimes newer display drivers may not have a backwards compatibility for certain calls, ATI has been famous for this in the past.
I’ve had CS3 working on Vista HP 64 with no real problems, sounds like a video problem, try playing with the video driver versions, if not the latest, try updating, if the latest or recent you can also try rolling back to older versions.
