Right. But that's the part that -- at this point in time -- we actually doubt is possible.
Unlike other laser products on the market, the FB3 actually requires to be constantly fed by the PC in order to give output. There is no local "memory" or double-buffers. The moment that software stops feeding the FB3, it will terminate it's laser output. We have done a lot of tests to make sure that happens.
As DZ wrote, there could be a problem with your particular FB3. And there's another point to be made -- you wrote "When LivePRO errors out or any of the FB3 apps stop working". That's certainly not something we've heard much of, so it does make me wonder if you have some specific hardware problem, or if there is a problem with the USB port on your PC.
But again, here's where contacting us comes into play, so we can explore all of this -- explore what kind of PC you have, what kind of USB "root hub", cabling, and other factors which might be leading to a software failure. I'd also like to see if it's really possible for software to fail in such a way to get a static beam out of the FB3. In all of our testing, this was never the case, and we've never heard of it happening before.
