I'm using eVC3.0 and have similar problems with the 8100. The client just
says that it locks up at random places and there doesn't seem to be any
consistent pattern with what they're doing when it locks up. They just soft
reset and go back into the application. I haven't found anything yet, but
it does look like there might be a problem with the 8100?
