I use a wireless mouse (with an USB receiver), and my notebook's OS is Windows 7 Home Edition. When I newly bought this, I found that the scrolling speed is quite slow, so I set it from "1" to "4" in "Wheel" of "Mouse" in "Control Panel". However, whenever I restart the computer or the mouse, "the following number of lines at time" sets to "1" again.
How can I solve this?
