unexpected reset problem

I have started using FCPx 10.2.3 after a year due to illness. I am getting an unexpected reset error when my monitor goes to sleep on a nMP (2013). I have been working around the issue by not letting the monitor sleep. Is there an easy fix for this? I also had the issue in 10.2.2

Thanks

If this does not make sense, I blame the drugs LOL
