From the developer:
Spyder3Utility is a monitor calibrator for photography. Some text items in the Utility menu (access this by double-clicking the Utility icon in the Windows system tray; or clicking on it, in the OSX menu bar) are grayed out (disabled). These text items are status indicators that will change from time to time, based on the state of Utility, Elite, the sensor, ambient light levels, and the display recalibration reminder interval.
