When using the COOT (0.9.8.5 EL) on a Mac, the behavior appears to have changed for manually rotating a fragment (Rotate/Translate Zone/Chain Molecule tool)
When activated, the pop-up window allows me to use the sliders to rotate or translate. That works as advertised. However, I used to be able to hold down the Control key (on Mac OS) and then use the LeftMouse to make the same minor adjustments to the rotation and translation. On current version, if I do that, it appears that rather than the center of rotation being the last atom chosen, the center of rotation is somewhere else (it is not the center of mass of the fragment). Thus, using Control-Mouse causes the fragment to fly off as it is rotating around some distant origin rather than the molecule itself. Edit > Settings > Rotate Translate Zone Mode > provides two options (about fragment center and about second clicked atom) and neither seems to help. Again, this tool works fine using the slider bars. Additionally, Control – LeftMouse ON an atom to move an atom works fine. It is just the Control – LeftMouse NOT ON an atom in an effort to rotate the entire fragment that is problematic. Is there a setting to return this to operational. Thanks for any suggestions.
