answer:Your best bet would be the control panel for the mouse itself. A gaming mouse, with extra buttons, will likely have a control panel that overrides the generic one that comes with Windows. Or it may look the same, but it would have extra tabs for the extended features. Compatibility mode does nothing for a device driver. You should install the Windows 7 driver as such. I’m not familiar with the model you have, but you can sometimes program the extra buttons to be interpreted as keystrokes or other application specific actions.
