Hey everyone, after googling this issue I found that several people experienced their cursor jumping to random areas of their screen (with the trackpad). However my cursor isn't jumping randomly, it's ALWAYS going to the upper left corner of the window where the red Exit button is. I've accidentally closed my windows so many times! I was wondering if anybody had a solution to this problem? I have tried looking through system preferences for any new or strange settings but found none, and someone suggested going to the System Preferences > Universal Access, and checking the box for "Enable access for assistive devices". But they said they had Steermouse installed and I don't know what that is. I tried this solution anyway and it didn't work - my mouse still jumps. HELP?
