Hello Everyone, I am using an Apple bluetooth mouse and frequently have a problem of the mouse pointer suddenly taking off to a cormner off the screen and, with "active corners", have the screen saver or other expose setting activate. This happens constantly and at times when I am NOT moving the mouse at all (but mt hand is resting on it). I am using a mouse pad which does have some graphics on it; I thought this could be the problem. Has anyone else experienced this sudden, unexplained mouse movement. Thanks in advance for any and all advice.
