i'm really not sure what happened. i used to use the arrow keys on my laptop keyboard to navigate up and down the pages. now when i try that, it doesn't scroll smoothly... a cursor appears and goes down the page line by line. its very annoying and, like i said, it never did that before. i don't remember changing any settings; i've gone back and reset my mouse and touch pad and all that jazz to default, but it didn't help.
