WCS, like Windows XP, still does not load calibration curves from monitor profiles. This one deserves a little background... After you calibrate and profile your display, the profiling software saves the graphics card's calibration curves inside the monitor profile so they can be reloaded on reboot. The Mac OS has reloaded these curves automatically since OS 8 but on Windows, a third-party utility is required. This is open to conflicts as two different software packages might fight over loading curves (LUT wars). Also, selecting different display profiles in the displays control panel does not load each profile's calibration curves... cumbersome at best. This is an odd oversight as it is a simple function and one that really should be performed by the OS.
