Thanks for the hint. I had indeed a small utility running in the background that I almost forgot about ('KatMouse.exe', it allows to scroll unfocused windows with the mousewheel when hovering the mouse cursor over them) which turned out to be interfering with the test window. After closing KatMouse.exe, everything is now working fine for me, even prior versions of dispcal/dispread/dispwin. So, not an Argyll issue. Sorry for the false alarm.
Hmm. I tried installing KatMouse, and no matter what I tried, I still couldn't reproduce the problem. Do these versions <http://www.argyllcms.com/ccmxmake.zip> work for you, even with KatMouse running ? Graeme Gill.
