|This happens all of the time if you are using a wireless mouse since without the wire on one end, many mice look about the same both ways. All you have to do is turn the mouse around so the front is facing you and the movement is reversed. It is the strangest feeling the first time it happens to you though. You typically move the mouse in a small circle to locate the pointer and then begin to move it where you want... When it goes the wrong way your brain goes WOOOH HOLD ON THERE!!! Then you stop, look at the monitor, look at the keyboard, look at your HAND, and finally look at the mouse. Your mouth opens, closes, and you proceed to turn the mouse around the right way. If you are lucky, you just shake your head, if you are a control freak or just weird, you just might start to shake all over.|
You have to be a little bit crazy to keep you from going insane.
