Just to make the point that you are not alone, I have observed the same
issue on Mac with CCP4-installed Coot 0.8.9.1 using latest OS and
Xquartz. This started happening with a recent update.
Interestingly, the 'Edit Chi Angles' dialogue now allows us to modify
non-chi angles as well (not sure if this was intentional), but only for
some residues. For example, when I click on a Leu or Cys, I am given the
options to also modify "C <--> CA" and "CA <--> N" torsional angles,
generally known as psi and phi. But with Asp, I get no such options to
modify psi and phi. Interestingly, with Glu, the only angles I am
allowed to modify in the "Edit Chi Angles" dialog are psi and phi angles.

For some residues - such as Glu - the dialogue only shows the C <-->
CA angle. If you tick the 'Add Chi Angles for Hydrogens' box, it adds
CA <--> N.
I've just compiled Coot on the same Mac using Fink, and the dialogue
for this version of Coot shows CA <--> CB, CB <--> CG, and CG <--> CD
angles for the same residue.
The CCP4 version which misbehaves is 0.8.9.1; the working Fink version
is 0.8.9. Both are running on OS X 10.11.6.
Has anyone else experienced this? Any suggestions as to how to fix this?
