It's not analog, it's digital. The X & Y are quadrature encoded (2 bits each) and the mouse button is just a switch closure.

Wait a sec, you get the boot disk ICON but does it boot? If it isn't booting to the desktop then they mouse should behave as you describe. You should see the menu bar at the top and the floppy ICON on the desktop as well as any windows that might open. If you are not seeing this you need to get a working boot disk. >>> >>> I have tried the "old" mouse (one that was given to me) and one of >>> the "new" mice.
