So I've had two of these old MS Intellimouse optical 1.1 mice over the years, I've always loved the button layout, having the back/forward buttons on opposite sides, rather than the left side like most mice these days. Unfortunately this one has started double clicking whenever I left click just like my original one started doing. I went looking for another one and was heart broken to find out they're very hard to find due to being discontinued. Did anyone else here use one of these and have to move onto something else?
