For several months, my mouse and scroll wheel have taken on a life of its own. At random times when I'm scrolling up or down, my screen will jump to a previous page (or pages). Other times, the size of the text will change. When I left-click the mouse to try and correct this, everything on the screen will become highlighted (turning to blue).
In fact, the first time I attempted to type this post, all my letters suddenly began typing in the upper case even though the caps lock was not on.
In order to completely get out of it, I have to restart the computer.
Does this sound like my mouse is malfunctioning? It's less than a year old and is a Hewlitt Packard (still under warranty).
