Jamie Roberts Posted February 15, 2007 Share #1  Posted February 15, 2007 Advertisement (gone after registration) Ok--so I know everyone here except for me (and maybe Scott K?) are using Macs, so you can gloat now...  FYI-Windows Vista apparently has a serious flaw with the way the new colour management engine interacts with the OS.  It's nothing that MS won't fix in the first Service Pack, no doubt, but if I were you I wouldn't even think of upgrading till they fix this (course, it's ok on a laptop, where you can't really do critical colour work anyway).  But this news comes from Steve Upton at Chromix (http://www.chromix.com), and he actually worked with MS to develop their new WCS color management module in Vista.  It's evidently a great new color system; the first time MS has worked on color for years and years, and state-of-the-art in some ways.  But--and this is a big but--it looks like they messed up big time in this first release of Vista.  Every time the OS asks for authorization (like admin rights to install a program) the new interface dims, and the LUT from the calibration of your monitor is lost, and evidently DOESN'T get re-loaded. Talk about a killer bug for graphics apps!  IOW before the "dimmin" you were color managed; after the interface comes back, you're not! You have to reboot to re-load the calibration, which will get very old very quickly.  In practice, this means you will never know if your monitor is actually performing properly, or not.  So wait till SP1 at least; I'm going to wait for the all-clear from Chromix, personally.  Here's the summary from a Chromix newsletter published today:  "In Summary  WCS has the makings of a very capable color management system. It seems to be able to fit into traditional ICC-based workflows and then quickly flip into WCS mode for some of its newer features and capabilities. The architecture certainly has a future. It's the present I am concerned with primarily.  Due to Vista's non-handling and mishandling of graphics card calibration curves it is next to impossible for a professional user to be confident that their system is properly calibrated and displaying color correctly. For this reason I do not recommend Vista for professional workflows at this time. When Microsoft addresses the calibration-clobbering bug in a future service pack then I think Vista will make an effective platform for high quality color production."  BTW--if you don't profile and calibrate your monitor, or you use a laptop, or you pay a lab for colour correction--never mind; as you were Link to post Share on other sites More sharing options...
scott kirkpatrick Posted February 15, 2007 Share #2 Â Posted February 15, 2007 Just one more reason to wait until no resistance to Vista is possible. (I use PC's, mainly a T43p laptop, calibrated with Eye-One, which has a pretty good display if I remember to keep it clean.) Vista's enthusiasm for digital rights management is another reason that I haven't been in a hurry. The final reason is that upgrading the installed OS on an existing PC, rather than using a MFR's installed version has usually cost me a month of hard work in the past.

Guest stnami Posted February 15, 2007 Share #3  Posted February 15, 2007 Here MacDailyNews | Microsoft Windows Vista demo goes bad  and there was the guy who asked his vista based computer to wipe out all information on the computer... so it did.......... clean as a whistle   .. but lets not take these things too seriously Link to post Share on other sites More sharing options...
cbretteville Posted February 15, 2007 Share #4  Posted February 15, 2007 Thats a propper Ooooops.  One thing that will help some is to switch the LUA (Limited User Access) "feature" off. That will reduce security some, but will keep the @£$€!$€!! popups surpressed.  As software is propperly migrated to Vista things will improve and LUA may work as intended without driving users crazy. But the question is if the lag here isn't enough to cause most people to switch the thing off.  - C  PS: I'm on Windows too, but have no plans to switch to Vista. I want to see how things pan out and wait for at least SP1. Why should I when XP does what I need. If it works, don't fix it! Link to post Share on other sites More sharing options...
j. borger Posted February 15, 2007 Share #5 Â Posted February 15, 2007 Thanks .....another very good reason to stay away from Vista as long as possible:) Link to post Share on other sites More sharing options...
okram Posted February 15, 2007 Share #6 Â Posted February 15, 2007 Do you know that if you put the computer to sleep or hibernate on XP, video LUT is not loaded? This is not a new thing, and I hoped that Vista will solve this idiotizm. Color applet is a bad excuse for a program, also. I tried to solve this problem many times. The main issue is that you dont know it is not loaded, unless you look very carefully (even then). So I gave up calibrated monitors on XP, and will go for MAC.

johnjs Posted February 15, 2007 Share #7  Posted February 15, 2007 Advertisement (gone after registration) Possible solution? Turn off UAC (User Account Control) temporarily, calibrate color, and then turn UAC back on. -John  Edit: Just tried it, with UAC off Windows interface doesn't dim or ask for permission to continue. Make changes, and then turn UAC back on. Start>Control Panel>User Accounts>Turn UAC ON or Off. You'll need Admin rights to alter this setting, and a restart is required. I've never actually played with this setting in the last year of running Vista until now, it might prove helpful when doing other hardware or graphics related tasks which require no interference from the security settings of the operating system. -J Link to post Share on other sites More sharing options...
george + Posted February 15, 2007 Share #8 Â Posted February 15, 2007 I am one of those died-in-the-wool Windows users. Not yet on Vista, though I tried - and did not care for it yet. Â But on my reasonably uptodate XP system I have to recalibrate all three screens after every Restart. Â If any of you have a solution, please let me know.

george + Posted February 15, 2007 Share #10 Â Posted February 15, 2007 John, many thanks - you saved me a lot of grief. It so happens that I had this module since late 05 but never really used it. Then it got removed from the Start List - an you know the rest. It is back in now and will be of great use. Thanks again:) Link to post Share on other sites More sharing options...

egibaud Posted February 15, 2007 Share #12  Posted February 15, 2007 I was a Window user since 1988 .... until 3 weeks ago when I bought a MacBook  I never thought Mac users could have been so right telling me I should try Mac.  Do yourself a favour, bin your Vista, beleive me I did not beleive it myself until I used Mac OS X Link to post Share on other sites More sharing options...
