Sometimes, my mouse is making double clicks really fast. I think that I have noticed it happen to both the left click and the right click button.
I notice it most often when I'm doing intensive things, like scrolling through a turn-based game that I'm watching by clicking "next move" button, or playing action games. But I'm definately certain that it is not a mistake on my part. I tried to speed through a 300 move game, and got about 5-10 double clicks, that was for the left-click. And I think that the right-click started to double click at about the same time the left-click did.
I have had this problem a couple of years ago aswell, back then I just swapped mouse, but I hope I won't have to do it again.
Thanks in advance!
