I have noticed recently that when I release the mouse to take a shot, sometimes the mouse moves the curser to a different position and the shot is fluffed. Other times, the screen minimizes! This is very infuriating. I've changed my mouse batteries but it still does it. Has this happened to anyone else?

I have seen the different position but not screen minimizing, i would try a different browser but i don't know if their is a fix.
