Have an HP dv6 I got last summer, works great. Recently however, the touchpad has become incredibly sensitive. I can almost just blow on it and it activates, so I'm constantly opening pages I don't want, or the same page will open ten times. Just the slightest touch and it takes off on its own. I've gotten so used to it, I never use a mouse anymore and would prefer to keep it that way. Is there a way to adjust the sensitivity so it's more normal?
