Dell :: Better Tap Speed For 1545's Alps Pad?

i've searched around a bit and see i'm not the only one who hates this touchpad (just traded "up" from an 8 year old machine whose pad worked flawlessly), but no-one's mentioned my gripe yet:

the tap speed cannot be adjusted high enough to keep up with the taps when tapping the scrollbar equal to using the button. i use my laptop for newsreading so accurate line-by-line tap-scrolling is something i've come to take for granted, but on this machine

i have to use the button or deal with 2-moves-to-every-5-taps scrolling - unacceptable! especially when machines from 10 years ago are care-free. having this pad on my beautiful new Dell is like getting a new Ferrari with a loose steering wheel
