@gray @natty @Moon @chjara I remember this trash. You couldn't right-click unless your index finger was OFF the left-click side of the mouse, since it used touch sensors instead of two physical buttons to determine whether you wanted to left click (index finger touching left side, whether middle finger was touching right side or not) or right click (middle finger touching right side AND index finger NOT touching left side).

And the scroll ball was stupidly hard to actually turn...You had to push down on the mouse, inadvertently clicking it.
