I am currently using a BT mouse with my MBP. Its a dell BT mouse, and it is manufactured by Logitech. ( there are Logitech logos on the components ). The mouse works fine, but the extra features such as the side scrolling and the forward + back buttons do not work. There are no provisions to change this, or i can not find out where i would be able to change or activate these parameters. Thanks. any advise?
