For click and drag, don't use your index finger to both keep the button depressed AND move the pointer. On a regular trackpad you'd click the left button with index finger and move the pointer by moving middle finger over the trackpad; you can do the same thing here by clicking in with index finger and then moving middle finger.

Other than click and drag I never use the physical click, tap to click is where it's at. OSX registers tapping much, much better than any trackpad I've tried with Windows.
