There's likely a manual describing the settings (and how to change them hopefully if it's possible) under Start
(the orb in Vista) Programs
under a folder likely called something like Support
or something similar.
It also likely has its own settings application for those added functions and wouldn't be changeable through the normal mouse settings in Windows so you'd need to find the specific program if there is one and change it there if possible.
If it's a new laptop you can most likely contact Gateway by phone or email for free and hopefully the support staff member you get will be able to help you out.
