any update on Steve's "Authorization Bug" in Vista

[Brad_Stiritz]

Hi everyone,

Now that Vista SP1 is out, has anyone from Chromix checked into whether it fixed the “Authorization Bug” that Steve Upton discussed last year–?

As you use Vista, you are occasionally interrupted by the OS as it confirms you have the admin-level privileges required or confirms certain actions. As a user-interface effect, Vista dims the screen slightly while offering the user a password dialog. Unfortunately, this dimming of the display clobbers the calibration curves in the graphics card and they are not replaced.

Can anyone give a status update or further info on this please? Did Steve discuss the bug with anyone at MS? Were there any assurances given that it would be treated as a priority? Was there discussion of issuing a hotfix? If so, was a hotfix issued?

I’m asking all these questions b/c circumstances are pushing me towards 64-bit Vista, and I’m probably going to migrate in the next month or two.

All comments appreciated,
Thanks,
Brad

Service Pack 1 apparently has a fix in it for this problem. It does not seem to work 100%. Xrite has also published a fix/workaround for the problem of the calibration curves unloading:

From Xrite:

Microsoft has published a hotfix for the problem of the calibration curves unloading when the secure desktop launches in Vista. The fix is included in security update MS08-025. The calibration fix is only installed on Vista SP1 and later. If MS08-025 is installed on a non-SP1 system, the calibration fix is not installed.

If this fix fails to correct the problem, Windows Defender could be the culprit. Try shutting off Windows Defender by following these steps:

Navigate to Control Panel and then double click on “Windows Defender” to open it.
Select “Tools” and then “Options”.
Scroll to the bottom of the page of options and uncheck the “Use Windows Defender” check box in the “Administrator options” section.
Click on “Save” and then “Close” in the resulting Windows Defender information window.
Restart the the computer to turn off Windows Defender and check to see if the monitor profile loads automatically.

Apparently this has been around for awhile, but Xrite has this nifty little program for Windows (XP and Vista) where it displays your monitor profiles, allows you to change the active profile, and instantly updates the video card LUT. This can be useful to Vista users who need to confirm that the OS hasn’t dumped their color information.

This problem bugged us for about a year. We tried every fix we could find but no luck. The fix came finnaly when we upgraded our graphics card for Adobe CS4. The Nivida Quadro nvs 290 and nvs 295 graphics cards cleared up our problems. The 290 is not OpenGL so you will lose some of Adobes new features.
