Are you trying to say, with your poor English, heh, just teasing, that the left and right mouse buttons are reversed. When you click the left mouse button it brings up the right click menu and then the opposite for the right mouse button, OR, are you trying to say when you right click something them menu pops up on the left? Because when you right click something to bring up the context menu, it doesn't necessarily appear on the right. I need you to be a little more clear about what your problem is.
