Photoshop uses color management. Most other programs don't. Your monitor profile is probably off. Run Adobe Gamma again. Also, be sure you have your RGB working space set to sRGB, or use the generic Web Graphics Defaults preset. [Adobe Gamma is found at Start > Settings > Control Panel in Photoshop 6; at Photoshop/Calibrate folder (Windows) or Photoshop/Goodies/Calibration folder (Mac OS) in 5.5. Color settings are found at Edit > Color Settings in Photoshop 6, and at File > Color Settings in earlier versions.] -Jay Arraich
