Why on earth is there not a way to turn this off? I could be a bit understanding if there was just no UI option for this and I had to make an edit to an X conf file, but it's baffling that there just doesn't seem to be a way at all to turn it off. Some applications like Firefox let you change middle-click to autoscroll but that doesn't help outside of Firefox. I'm so worried I'm going to highlight my password and then absent-mindedly middle click and paste it into a chat twenty minutes later!
