purchased pen80 stylus from walmart, it doesn't work at all
I bought a pen80 to replace my old one (which still works, but only when plugged in).
this new one doesn't respond at all, or if it does, for a very brief instant. I've tried re-installing the drivers and restarting the computer, but the result remains the same. it does light up red at the buttons, but only for a few minutes after I've plugged it in. I'm not sure what to do, other than get a refund from walmart.
