I have noticed today that the track pad is acting weird. (early 2008) I usually use my right index finger to move the arrow around, but sometimes it happens that I may want to use the left index, and why not, the middle finger too.... But when I change fingers, sometimes i cannot get the arrow to move. Does the trackpad recognize the fingers?? I know it sounds stupid, but either my trackpad is broken, or it has some "mental issues" Please explain. Actually I am just trying now, and it does not work with my left hand... This thing is possessed !!!!!!!!!
