I have a Sony notebook computer and I can use a standard PS/2 mouse without any problems. I hooked up an IntelliMouse (wheel mouse with PS/2 connector) and I installed the drivers. For some reason, it appears that the mouse is picking up excessive noise when I move it (icons move, applications open and close). It makes no difference if the touch pad on the notebook is disabled. If I use a standard PS/2 mouse, there's no problem.

Any suggestions? Is there a wheel mouse that works?
