I am not sure if its just my machine, or if this is a general problem. I and working along and my trackpad works just fine for the most part. Then occasionally it just doesn't respond. I click and move around and eventually it just starts working. When it does this, I shift to Istat to see if the processor is pegging out or something but its still under very light load. Like i said, its quite sporatic, so god knows how long it would take someone to reproduce if I asked Apple to take a look at it. Most probable outcome would I'd get the notebook back in a week saying, "Sorry, we just couldn't find the problem" So, am I the only one this is happening to?
