Muso hangs and unable to stop process

[DuLac]

I am running W10 Professional. For the second time in a short period of time, Muso hung and stopped working. I then tried to
a) right click and close the program's window
b) stop service using Taskbar to get "The operation could not be completed" "Access Denied"
c) run command line as administrator and taskkill.
d) follow every hint I could find in Google but all to no avail
Eventually I had to reboot the computer to get rid of the offending process and restart Muso normally
I have no other details as as I said it only happened twice. This can be a Muso related issue but it can also very well be related to my installation only. I am reporting it just in case someone else experienced the same sort of problem. In any case should it happen again I will try collect more details.

Muso 2.6.3.0 on W10 had this happen. Was able to close window though. Event Log has:
Log Name: Application

Date: 17/11/2016 10:39:57
Event ID: 1002
Task Category: (101)
Level: Error

Is there any pattern here? Was Muso running remote perhaps, or in screensaver mode? If either of you could capture the phenomenon while running Muso with diagnostics on, I could perhaps glean something from the log.
