I just got a new computer (HP Spectre x360 13t) and I noticed that when Mulitplicity is running, I can't put the computer to sleep. It just immediately wakes back up. I don't have this problem on my older Dell precession m6400. My guess is maybe it has something to do with the new S0 sleep state?
Either way, is there a way to prevent this? I can reproduce at will. When multiplicity is running, selecting sleep results in it immediately waking back up. With Multiplicity unloaded, the computer goes to sleep as expected.
I should note that I currently have this set up as a secondary computer. I don't know if the problem is there if it's the primary. I will try it out.
