Comment 0 for bug 1245159

On a MacBookPro8,2, the track pad often fires off a click even when it is not pressed. This can happen when typing on the keyboard (not touching the trackpad) or when actually using the mouse but not clicking. Such events make it fairly unsafe to use GUI applications that do not have an "undo" function for each possible action. Nothing seems to make the false clicks more or less likely to happen.
