hello, I have a strange problem, it seems related to event handling. When I am in the terminal and keep a arrow key pressed and the cursor is moving, sometimes when I release the key, after a second or two it moves one position more, like if I was pressing it, but I am not.
Something similar happens with graphical windows when I am scrolling the page with the wheel, I scroll up or down, and sometimes after 1 second it scrolls by itself one "step" more. I cannot guess the reason.

thanks
