Thank you for clueing me in on Malwarebytes. It was creating another
problem which had been driving me nuts for several days.
All of a sudden, when I had multiple servers running MC, I was unable to
see the devices/libraries on the other servers on Playing Now.
Some of the remote devices/libraries would eventually appear, but not all.
I quit Malwarebytes after Startup, and all appeared as expected!
Running v 4.1, but no longer!
