This was mentioned 10x, but turn off the Expose side mouse button option. The side button on my old Mighty Mouse regularly cycled on/off for no reason. It would cycle rapidly like some cellphone static goes in and out then some days it would be fine.
The scroll ball always goes out too, but if you clean it then it comes back. Turn it upside down and rub a damp then dry cloth on the ball back and forth. Wha la. It works.
For fun and because the Mighty Mouse fails often, I turned it back into a one button mouse. Now we know why Apple stuck with 1-button for so long. And actually, even though I came from the Windows world, it's a nice change of pace to use a 1-button mouse.
