I've tested two Kensington PilotMouse Laser Wireless mice and the middle button only works occassionally.  I returned them for refund.  I think the problem is what you said -- pressing activates the side-to-side scroll which overrides the middle click.  I've also tried an MS Notebook Laser Mouse and the button didn't work either.  

I know that many other mice work --- probably the ones without the horizontal scroll.

Subject: [PyMOL] kensington three button mouse in mac book pro-issue


I am using Kensington three-button mouse on a Mac book pro (17") laptop. In pymol,

when i press the middle button (for translation), it switches to horizontal scroll. The translation function is not working!

Has anyone experienced similar problem?. Any fix or work around?
