Tested on my dell mini netbook.

Doubletap on the right button area functions as a right click.  It seems
to work as I'd expect.  Single-tap on the main pad area appears to work
as single left click (and double-tap here works as double left click).
Single-tap on the left button area doesn't appear to do anything.

Mouse movement does not work if two fingers are touching the pad.
Depressing the left button with one finger and moving the second will
initiate a drag action but the mouse pointer does not move; IOW drag and
drop is broken.  I could not get click-and-drag with two separate
fingers to function.

HTH,
Bryce
