Try this:
plug in the dongle in to a PC USB port, use your other mouse to get the dongle pass all the windows prompting to finish its driver installation.
put the battery in the mouse, press and hold the F button on mouse while press the Start button to power it up.
This will reset the setting back to default. move the mouse to see if it I works as a regular mouse which can move your cursor? If this is correct then that tells the mouse is ok, just that user didn’t use it correctly.
Let me know.
