I suspect the latter.

It's a Saitek Laser mouse. I checked these for polished surfaces and it's even 
working on glass if you stick some milky sheet _under_ the glass, which 
doesn't destroy the clean surface optic. (btw, the logitech laser mice didn't 
work on the described glass table!)
I have one spare in stock, I can put it in your letter box if I'm downtown 
next time (planned for this afternoon, but weather forecast predicts hail.... 
so not sure)

Best regards,
