Can't scroll through emails after opening first email
 

I had this problem before updating to 6.1 last week. The problem was fixed but now it is back again. What happens is when I open an email and then "ok" out of that email, when I go to scroll up or down to open another, the D-pad just doesn't seem to work. I have to choose the next email by touching the email on the screen. Anyone else experience this??? It is a real inconvenience!!
