I've been using the mouse for well...forever, and everything had been okay up until a few weeks ago. I'm not sure why it's happening, but it's actually a pretty annoying problem. I've no idea where the problem lies(KDE, X, kernel...I've no idea). The one place where this gets really annoying is when I'm using my image viewer. I'd like to be able to scroll through them without skipping half of them(and without using my keyboard), for the sake of convenience. If anyone has any bright ideas, please do speak up, because I'm quite frustrated by this point. (I know I mentioned only one place where it's an issue, but it also seems to scroll twice as many text lines in text-ish programs (id est kate))
