I have a new Microsoft basic optical mouse that appears to get lost on my
desk top.
The arrow travels on its own to the top right corner, or to the bottom left
corner. It does not happen always, but it's very, frequent, I have changed
the mouse connections from a USB port to the PS/2 connector without
improvements or changes. I have attempted to upgrade my software with out
luck. My OS is Microsoft XP home and I have a standard desk top computer.
