This happened with my old Logitech Dual Optical and with my new Logitech MX518 mouse. So I don't think it's a bug with the mouse.
I found out that this happens only in "List mode". -- Video player is starting twice when double-clicking on video file https://launchpad.net/bugs/93366 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
