I got the double-click issue. It's not a huge issue, but I notice it only when I'm trying to close quick-launch programs and it automatically opens a window of another program that filled in for the just-closed program.
Again, not a big issue, but it does exist. If I remember right, I'm using either the Lycosoa or DeathAdder. But I suggest going with the G400; MX518 is still my favorite mouse.
