During the last days it happened more and more that suddenly the mouse cursor freezes. It helps to put the Mac in standby and to awake it immediately. But it is still annoying. I have two mice, one for the left hand one for the right hand. One is a MS wireless Mouse 2000 the other one, a Logitech MX1100 R, that I use not that often, as the MS Mouse can be used with either hand. I have installed the latest Intellipoint Driver but the windows mouse page says: "no MS mouse found". What went wrong, what could I do?
