After you install a three-button mouse and its driver and restart Windows
NT, you may not be able to use all three buttons of the mouse.
CAUSE
By default, Windows NT configures all mice as a two-button mouse in the
registry.
RESOLUTION
To correct this problem, you must modify the Windows NT Registry.

system-wide problems that may require you to reinstall Windows NT to
correct them. Microsoft cannot guarantee that any problems resulting
