i know this is a simple question, but for the life of me i can't remember how
to change the scroll wheel setting to go from scrolling through 3 rows at a
time to one roll at a time. and before you say "go to mouse under control
panel"--did that three times already. there is no *obvious* way to change
the setting under any of the tabs. please help--it's driving me nuts. i
promise i'll write it down this time.

i'm using a (new) microsoft wireless mobile mouse 4000 in excel 2003 on
vista os.
