Have you had problems with your Mighty Mouse, thinking it only has right-click? Well, your problems are over, and it DOES have right-click.
Open up your system preferences. Click keyboard and mouse, then the mouse tab. Click the right side of the mouse which SHOULD be set to primary. Click it, and in the dialog, select SECONDARY. Then, when you click on the right side of your mouse, the right-click function should work. Hope this helps everyone
