OK, I took mine apart. The bottom line is all is very well sealed in there and what\'s being seen isn\'t circuitry. But for those who want to see I\'ll add a few pictures.
Here\'s the back panel off showing the metal shielding over the button assembly area.
With the metal shield removed you can see the thick rubber seals (gray)around the buttons and the back side of the wheel assembly.
With the pressure plate removed you see the box side of the scroll wheel assembly, the spring and ball bearing that clicks it as you rotate (green line) and double rubber seals that press against the pressure plate and seal in the assembly (red lines).
on to next reply
