Hi Antonio, Thank you for the program.
After running the program, it appears that no X-axis information is being received by the computer. Also, very strange, is that the Y-axis numbers continue to increase regardless of whether I move the mouse up or down. If I'm not mistaken, the numbers ought to get smaller as I move the mouse up, and larger *only* when I move the mouse down. I'm not very hardware-savvy but I will look into what you suggested and see if I can make sense of it.
