Remember that on the left or right motion I received two presses and two releases for two different "X-buttons". This same thing happens for other physical buttons on the beast. Fortunately the two main buttons give just button 1 and button 3 respectively. Another button just gives button 2 and the wheel rotation give button 4 in one direction and 5 in the other. So it does work as a wheeled mouse if I ignore all the other physical buttons. allan
