Hi, First once again thank you for this amazing software. Back in July, I did a few flash tests for a web site. http://www.focus-numerique.com/test-1105/eclairage-test-flash-bowens-gemini-travel-pack-2x-400-1.html The Spotread -f option and the Colormunki was a great help. I retried yesterday with an up to date Argyll and this was not working that great anymore. The measures are either bad (ambiant light rather than flash light) or saturated (even when the flash is far far away). The few measures that seamed to work didn't gave the right amount of light. Spotread -f also operate differently. I now have to press spacebar and the soft is waiting for the flashlight. Before was press and hold the Munki button. I reinstalled the 1.1.1 version and everything worked fine (small flash distance ok, calibrated light amount measurement, quick and working measures). Thanks by advance and sorry for the bad english, Matthieu DUBAIL
