I'm not sure, how would I go about checking that? It has worked perfectly since January, and 2 hours yesterday before it died. I have not updated any drivers / software in the past month easily. I've also turned on the command and help line, and get no errors or alerts from either, when choosing a square options box, although it does flash the 'thinking' icon, the little watch, leading me to believe it is trying to do /something/.

If there are any tests that anyone can think of, I'd greatly appreciate it!
