Although the Envy Touchsmart has a separate numeric keypad, there is no key labeled Scroll Lock, but somehow I turned it on and now I can't figure out how to turn it off.
At least I believe it is a scroll look button problem because each time I hold down the lower left corner of the touchpad and move the cursor to highlight some text in word or any other program the cursor changes shape to a small dot with a small upward pointing arrow head above the dot and another below pointing downward.
