Joe,
Your friend apparently doesn't have a broken mouse or screwed up mouse
settings.
Swap your mouse with your friend's. See if theirs works correctly on your
machine and if yours works correctly on their machine.
If yours works correctly on their machine, then it is probably some
setting(s).
If theirs does not work correctly on your machine, then it is probably some
setting(s).
Look at the settings in Mouse Properties on their machine and make sure that
your settings are the same.
If yours does not work correctly on their machine then something is wrong
with the mouse.
Get a new mouse.

Hope this helps. Let us know.
