I have downloaded PyMOL v18.104.22.168 from sourceforge and installed it on my Ubuntu 12.04. It works very well. Recently I noticed there is a problem when selecting residues from the sequence panel (Display -> Sequence). If I select multiple residues using mouse in the sequence panel, only the first selected residue is highlighted in the corresponding structure. Then rest selected residues are not highlighted. But if I disable my selection and enable it again (e.g. by clicking on the selection name in the control panel), all the selected residues will be highlighted. This is different from PyMOL 1.5 or older version, and I don't think it is a feature (I read what's new for 1.6 :). There is no any warning or error message output on the terminal. Has anyone had similar problem?
