Lately my iBook has been flaking out. My HD churns for hours at a time, the fan runs when it hardly ever did before. (now running 10.3) The thing that is the worst is the trackpad button just stops functioning like the computer is locked up. The KB and trackpad works. Even my mouse stops clicking when it happens. I can't do anything except command+Q all my apps and hard reboot. Even then, sometimes I don't get the botton back. I just shut it off for a while. Lately I have been trying out some new apps but I can't pin anything down to a specific install. Anyone else lost mouseclicking "randomly" before?
