Looks like the undo button on Coot doesn't work. I installed Coot-0.8.6 on MacOsx El Capitan. Anyone knows what could be the problem?
Perhaps you have started coot from a directory to which you do not have write access? What does it say in the terminal? That should be pretty clear about the problem.
Or where to report the bug?
If this is not a CCP4 problem, then the Coot mailing list (on Jiscmail). Paul.
