I have 2 trackpad questions. 1) Is there any way to make the "scrolling" area larger?? 2) Are there any covers for the trackpad to make it less sticky? Since it's painted in the same thing as the rest of the area it seems to be hard to actually move your finger on it. I know I had something like this for an old ibook that got "sticky" after awhile. Thanks! (and I tried searching for the answers, but the search feature doesnt seem to work very well)
