Is it possible? Our board, an ETC Express 125/250 run by an Emphasis system, has a funky trackpad. Lately it has been constantly picking up ghost input and has made individual channel selection next to impossible (I had to tweak a cue using the cue sheet in Blind yesterday -- a workaround, but not a preferrable one). So, I want to know if there is a way to just turn it off all together. We don't use it that much anyway, and it would save us plenty of headaches.
