One, your Computer doesn't contradict what tasks you click on, or how they perform; That's up to what you do with your mouse, and or how much Random Allocated Memory (RAM) you have, and your Central Processing Unit (CPU- The Brain of your computer, basically.) You can't increase something your mouse sits on, whether it be on your desk or something in that manner, you'd have to buy a larger mouse pad; So, that leaves A & B. Um, if I'm not totally mistaken you can do both in Mouse Properties, but.. I'm about 75% sure that it's A.
