After updating to 10.3 I have noticed that something named "n" when shutting down computer after being up several days hangs. This "n" shown in title bar when shutting down computer (End now Windows dialog) has to be part of ZCM.

Have searched for "n.exe" without results and nothing is shown in Event log.

Can someone confirm "n" being a part of ZCM and if so what is it's purpose?

Anyone else seen the same?
