Query: Almost a great mouse, but one big problem

I love this mouse in every way except one. And unfortunately it is the most important thing. The mouse will work fine about 90% of the time then it just jumps across or up the screen for no reason. I have followed the installation directions and I have it 8 inches away from any electrical device and it is only about 8 inches from the mouse and it still jumps. I would move it even further away from electrical devices, but the cord is too short.
