Adriano,
That is interesting that you bring up "calibration enabled" button. The
first few times I used PreCal and Optical, I wasn't sure if the setting
should be enabled or disabled. I called ColorVision tech support and
they claim the "calibration enabled" button should always be checked.
They claim this is true when running PreCal as well. Personally, I
think the "calibration enabled" button is the culprit. I will have to
do some more experimentation to determine if it is truly the problem.
What is the consensus? Do most have the "calibration enabled" button
checked when running PreCal and then Optical?

You check the option "Calibration On" (Optical window) every

I don't belive that, but is not impossible.

If you change the monitor profiles, your display change too?
