A strange thing with one of our Eos consoles ... occasionally, the Eos software will stop responding to movements of the level wheel. On some occasions, it's been observed to 'come back to life' of its own accord after a period of time. On other occasions, I've come out of the software into the shell and launched the face panel test, established that the wheel itself is working fine, then restarted the software at which point the wheel works OK again. Any idea what may be going on here?
