Hi Alessandra,
I too have the same thing. When I connected the mouse to the PS/2 port
using a adaptor, I had only one listing under Mouse. Then, when I
changed it to a USB port, I got two. Moreover, the cursor moves to the
top right/left corner on its own. Is that a hardware defect ? If so,
can we claim a replacement? Let me know if you know anything? Thanks in
advance.
