I have a Powerbook G4 1.5 Ghz 12". My trackpad ramdomly selects items on my desktop and so forth as I move the pointer around. This is extremely frustrating, for I can't get anything done without grabbing things I don't want, nor can I surf the web without inadvertantly clicking various links. I keep messing up my programs, hiding and showing things, etc. I hope there is a setting that needs to be adjusted that I don't know about-I really don't want to have to send this back.
