After installing this update I can no longer use System Prefs>Monitors>Color in the 'expert' mode to fine-tune the color and gamma on my 22" Cinema Display running on a Radeon 9800Pro Mac Edition under 10.3.6

The 'expert mode' wizard freezes when you attempt to adjust color or gamma at the first screen. Force quit not possible as it is a hard freeze requiring use of the power button to restart.

ATI's latest (4.4.2) update is the suspected cause as the earlier update allowed fine tuning of the display, even after the 10.3.6 update wass applied.
