David, I decided to try a test to see if I could confirm that each 
monitor is indeed being loaded with a different profile and that it 
is the one assigned to it using the WinColor applet.

After booting the machine, I used the applet to assign a profile to 
the secondary monitor which caused the monitor to produce a very dark 
image.  I set it as the default for the monitor.  

I then rebooted the machine.  During the boot sequence, the 
appearance of the monitors changed as follows:

1. Shortly after the desktop appeared, both monitors changed to what 
I am assuming is a no profile state.

2. Later, the appearance changed to what I know both monitors look 
like with the profile for the primary monitor applied.  I would guess 
this is Win XP or the NVidia driver applying the same profile to both 
monitors which is the expected behavior since I have a single video 
card.

3. At the very end of the boot sequence, the secondary monitor 
changes appearanceto what matches the dark profile I assinged to it 
using the WinColor applet.  The primary monitor does not change.  
This, to me says that the applet has loaded a different profile and 
applied it to the one monitor but not to the other.  I have the 
applet in my startup folder with the "/L" parameter so that it runs 
with no input required.

I do not know what the applet is doing, but it does appear to be 
applying separate profiles to the monitors.  In my case, I built the 
profiles using the Spyder2 and gave each a unique name based on the 
monitor type,  I have assigned these profiles as the default profile 
for each monitor using the WinColor applet in interactive mode.

For the record, my video card is an NVidia Quadro FX 3400.  My 
primary monitor is an IBM C220P CRT and the secondary is a Dell 
1905FP.

Is there something else you would like me to check to help answer the 
question about whether or not the applet is applying the unique set 
of corrections to each monitor?
