the most probable cause would be a broken wire in the cable so that it is breaking and making contact as the mouse is moved.
It would be possible to replace the cable by using a standard usb cable,cutting off one of the plugs and soldering the wires in place of the originals.
do you think that is the only solution? couldnt i try straightening or bending the wire so that doesnt happen? id kinda rather not cut the cable and try to solder cables.
