I went through the same puzzling situation with my D800E that shares a similar layout to the D600.
I think Brian has the right explanation: "… inadvertently pressing the Multi-Selector control“
My younger son and I are left eye shooters as my older one is a right eye. I discovered that we were not the only ones to experience this effect as that it is very frequently observable by left eye shooters in the beginning.
This is a "getting used to" issue. You will be better off if this is your only camera. But we are working with other cameras with other layout so it will less easy for us.
