[PyMOL] 2-button mouse problems

[Fergus B. <f.b...@au...>]

I am using a two-button mouse and have selected 2-Button Editing from 
the mouse menu but am having trouble atom-picking etc. When I click on 
an atom another atom somewhere else on the molecule is selected! I am 
using v.80 and my PC is a Dell OptiPlex GX200 PIII. I have tried 
reinstalling Pymol but this doesn't fix the problem. Any advice?
Thank you.
