Friend of mine has a Macbook and his mouse cursor always "clicks" after he doesn't touch the trackpad for about 5 seconds. If he's on a web page and moves the cursor over a link and then sits back, after 5 seconds it selects the link. It does it for any button in the system, not just web pages. So whenever he finishes moving the mouse, he has to move the cursor to the side of the screen over the desktop so that it doesn't accidentally click anything. Ideas anyone?
