boleyd: PhilChorusch01 is talking about going into your operating system`s preferences and modifying the global settings for all programs. Modern programs don`t handle the mouse at all; they leave that to the operating system and just use what the OS tells them. This means that the programs don`t need to be modified to change mouse settings, only a few values in some data file maintained by the OS (the infamous registry on Windows systems), and the Control Panel, as Windows calls it, is where you find the program to change those settings. Does this clear things up for you?
