I am inclined to think it is the antivirus but we got more than one report of Adagio no Responding (any module) and I was thinking it might be a Windows upgrade. One of the users just migrated from Windows7 to Windows 10 but also started using a new Antivirus.

Just clicking on Adagio after it has been inactive for a few minutes makes it stop working. I did change the network card not to go to sleep also.

I didn't see anything unusual on the Task Manager.
