Default How to make calibration color profile stick in '2nd identity'?

Calibration in Vista is less stable than XP.
This is simply a fact that SP1 does not correct and if you have not noticed
this on your own then you should.
Operations that bring up the UAC, and many other advisory Windows as well as
certain programs, will unload the calibration data from your video card.
The only time I ever experience unloading of the calibration data in XP is
when playing high end 3-d games, e.g Crysis, which take over your video card
settings and do not resume all your prior settings when you return to the
Windows desktop.
This is very easy to verify on your own.
Simply run the Spyder calibration utility until it is at its first step and
simply turn the program off.
This will reload your calibration data.
If you see a change in your screen image, signifying reloading of the
calibration data, then you have verified Vista's instability with regard to
color profiles.
The bottom line: before you run Photoshop in Vista it is in your best
interest to make sure the calibration data is loaded and running, regardless
of identity.
Unless you are pursuing color managed printing calibration does not matter
anyway. If you are pursuing color managed printing then it behooves you to
make sure your settings are correct before a printing run.
