Hi Steve,
In the JMRI Pref's the jmri-managers.defaults are set to Loconet.
It is set to Loconet, PR3 Standalone, Com15.
If I change the prefs to Loconet to internal & save & restart, they reset to internal.
If I do not restart it stays at Loconet, but I can't program anything.
Dick, sorry, it is the latest at 4.13.2 Java 1.8.0_161.
Like stated earlier, when I change it to my DCS240, it works fine.
My computer is on the other side of a wall from my layout.
Hence the PR4.
Jay
