Hi Graeme,

I'm using Argyll CMS v.1.6.3 on Windows XP SP3 x86 platform to calibrate 
display on a
notebook using i1 Pro 2 instrument.

During calibration process (iteration 4) dispcal asked me to re-calibrate 
instrument.
Here is dispcal message:

Patch 73 of 96
Sample read failed because instruments need calibration
Place the instrument on its reflective white reference Serial No. XXXXXXX,
 and then hit any key to continue,
 or hit Esc or Q to abort:

So I placed i1 on the reference and performed the calibration and it was 
performed OK with
"Calibration complete" message. After that I was needed to place i1 to the 
monitor again.
I expected a pause after the calibration so I'd have a time to do it. But 
dispcal
restarted the measurement process again immediately after the calibration (the 
test
windows was flashing by red and green colors) and some measurements were done 
while
re-positioning. So worst case Delta E in this reading was ~315.

Is this behavior is normal, or may be better to pause dispcal until correct 
re-positioning
of the instrument on the screen?

Recently I used i1 Pro 1 (old) version and dispcal did not insist on 
re-calibration.

Regards,
Ilya Dedinsky
