problem with USB wireless mouse

[20Five]

well, this never ending saga continues..

I drained out the battery completely, then recharged it for a few hours.. (should be plenty of time for it to be full)

Im not even sure this had anything to do with the problem, but now I am able to plug in my mouse receiver into the USB port and it activates... theres one MAJOR problem which is still highly annoying.. now when I move the mouse, it only scrolls from side to side.. it will not register any up-down movements at all..

any suggestions as to what would be causing this? Im about to say forget it and go drop $30 on another!
