J'ai FINALEMENT figured it out! On my Asus machine, au moins. Allez dans Panneau de configuration, like Browning IT said, but instead of clicking on the "Mouse" option, cliquez sur "Asus Smart Gesture" instead. Under the Two Finger Column, vérifiez le box next to "Content moves reversely with your finger's direction." I hope this applies to your model. J'ai un Flip. That took me 2 days to figure out!
