That must be really annoying...

What do you have set in the Spyder Utility Preferences for "Video Card" > "Load Video Card Look-up Table (LUT) Every"? 

I wonder if setting that to something other than "Never" might do the trick?

Gina:

MS has incorporated various safeguards into Win7.  Many of the things 
we could do with XP
are difficult to accomplish in Win7.  Windows has so many weaknesses 
and backdoors, for
security reasons, many operations in Win7 have to be executed as 
administrator.  Another
issue is file permissions, they locked a lot of things down.  I can't 
remember the correct term,
but there is a way to lessen up some of the security stuff.

I haven't had this problem, since I'm running XP on my main computer, 
but I've had to do a lot
of tweaks on one of my Win7 boxes in order for things to run right.

You would think that since you are the only user on the computer, you 
are the administrator.
Unless you specify to run a program as "administrator," you aren't.

I know this isn't a good answer, but might explain some of the problems.

I meant to ask this when I posted my first reply but forgot.

I'm also running Win7/64bit and I'm curious about what software you were installing that caused the problem? When I asked on the list about the Spyder Utility Video Card prefs options, David replied that some software can muck with the LUTS and the Video Card settings can help to resolve this. I've not run into the problem--so far--but it would be good to have a heads up as to which software might cause the problem.

Also, will you post back to the list what you find out from Datacolor support about the problem?

Thanks!
