I am having a problem with the scroll wheel on my Logietch VX nano mouse, and Logitech told me to send it in, but I want to check to see if I could fix it myself, but I unscrewed all of the screws that I could find (the two behind the battery cover) and I can't get it apart, so I need help figuring out how to take apart my mouse. Does anyone know how or could figure it out?
