Graeme,
I am having difficulties running ArgyllCMS with my old Spyder2 on Windows 7
64-bit. In a nutshell, when I attempt to do a calibration after doing
interactive adjustment of white point or level, I get bad and inconsistent
values for black XYZ and the calibration fails. However, when I skip the
interactive monitor adjustment, the black values are normal and calibration
can proceed successfully. In all cases, the XYZ values for the other
colors appear normal and consistent.
This problem showed up while I was using dispcalGUI with the interactive
box checked. A long interchange between me and Florian Hoch regarding this
can be found here:

After Florian said he was "mystified" I went back and ran ArgyllCMS from
the command line performing tests in which I skipped monitor adjustment and
also performed the adjustment before going into calibration. Here is a
short example from runs which summarize the results. The first run I
skipped the monitor adjustment. The second and third, I did the
adjustments of white point and level. As you can see, I terminated each
run after the sensor calibration stage had ended.

This may be, as Florian said, an isolated problem for my hardware. I would
appreciate your insight.
