My students have observed that selection of atoms is sporadically unreliable. They'll click on a carbon atom at one of the molecule, for example, and a hydrogen atom several Angstroms away will become selected. We used to encounter this issue regularly, and I thought that it had been resolved (I haven't had problems with it myself), but several of them have brought it to my attention this semester. It appears to be more common among Windows users, but this observation might just be anecdotal. The students can work around it by clicking atoms in the indexed atom list, but obviously it would be preferable if they could just click on the molecule. :)
