We are having problems with our keyboards - they do not work consistently. On some days, the keyboards will work. And on other days, they do not work - they are simply frozen, and do not work at all. We reboot the computer and start over, and it doesn't help anything. Then after a few days, a keyboard that was not working will all of a sudden start working again. But then after a day or so, it will freeze up again. Right now, all 4 keyboards we purchased are not working - yikes!!!

To clarify: we are using the DirectIN-PCB keyboards. We are using the keyboards while running a study in DirectRT, version 2008.2.103.1115 (I think that's right....there might be a typo in some of those #s). We use Macs, but we are running Windows 7 on the Macs using Boot Camp. Is this enough info for starters?
