Hi Again,
Thanks Jason for the update. Turns out PyMOL is not broken, but undo is simply
turned off. See below for details.
In version v1.5 we added a better undo. However, to stop it from eating up all
your RAM we disabled it for very large systems like proteins. Since it's PyMOL
you can always change this via the settings. Before you load and edit a large
molecule, please type,
set suspend_undo_atom_count, 0
This setting when set to X will allow undo on objects with fewer than X atoms.
If set to 0 it's unlimited and thus works on all objects. So,
set suspend_undo_atom_count, 2500
will allow undo on objects with 2500 or fewer atoms.
Undo prior to v1.5 could only undo 15 levels of atom conformations across one
protein. Now, undo can handle the following changes:
* conformational changes
* multiple object support
* addition/removal of atoms
* addition/removal of bonds
* addition/removal of fragments
* addition/removal of objects
* changes in valence
* changes in atom types
* editing discrete objects
* full support in the Builder
Cheers
Joel

Subject: [PyMOL] Can't undo anymore
Hi All,
In previous versions you could move a torsion angle (Ctrl-W click) and if you
selected the wrong end of the bond, you could undo this. Now it seems that the
undo is deactivated. Is it possible to have this reinstated? It was very handy.
Currently on 1.5.0.4 on Windows
Cheers
Joel
