Hi, I've uploaded a fix for this - <http://www.argyllcms.com/disptools.osx64.tgz>, containing dispwin, dispcal & dispread. The fix isn't entirely satisfactory, in that it seems that there is no way of fixing the problem if you run the 32 bit OS X 10.4 binaries on a systems >= 10.6. I've added a warning message for that particular situation. See if that helps. Graeme Gill.
