I got a new aluminum Macbook on Friday and every now and then my trackpad seems to stop responding for a brief second or so. Usually it just involves me lifting my finger off and placing it back on to correct it. Every time it happens my arrow just stops moving on the screen. I thought perhaps there was a "dead" spot on my trackpad, but it seems to happen randomly and on different parts of the trackpad. It seems to happen pretty regularly - Anyone else experiencing this?
