It is a laser mouse (Gigabyte M6980)
It's not a surface problem.
I have reinstalled it.
The problem might be in the memory of the mouse. It knows all the commands set in my PC on other computers, too. I don't know how to wipe mouse's memory.
Any idea? Thank you.
P. S. Here is a picture with two CIRCLES. One drawn slowly, one fast.
