Ok, just recieved my MBP and it seems lovely except for one thing....I was thinking the trackpad was awful but have worked out that it just seems to have a large deadspot right in the middle of the trackpad. If I try and move my finger from the bottom of the trackpad to the top it is fine for the first cm or so,then stops moving whilst my finger goes across the middle cm and then moves again at the top. Horizontal movement seems fine throughout though. Obviously this makes it incredibly hard to navigate. Is this a feature I need to turn off or is my trackpad likely faulty?
