Mouse pad arrow intermittently has an attached +/- rectangle
When moving the mouse pad arrow over the screen, a small rectangle with a + at its top and a - at its bottom appears at the tip of the arrow. The cause of this phenomenom is unknown and it happens out of the blue. When it does occur, a movement of the mouse up or down causes the screen to move suddenly up or down. This occurs without pushing the left or right mouse pad buttons. The rectangle can be made to disappear by moving the arrow sideways. It may or may not return when the arrow is then moved up or down.
I have not seen any discussion of this strange behavior on any forums. Any ideas on how to eliminate this behavior? Where can I get a mouse pad driver that behaves normally?
