I vaguely remember doing something to stop the 'googleads' thing that was interfering with my 'back button'.
I'm thinking that I've done something with my IE9 because it certainly is NOT speedy like the commercial implies. I really notice it here at sevenforums with that 'waiting for response' notice. And I'm sorry to say that I don't remember if it's always been slow. Have only had this PC for just short of 3 months & it's a whole new experience with Windows 7 compared to XP.
As I'm sure you can tell from my wording in questions & replies, I am NOT computer literate.
