Steve and Peter ¨C thanks for the suggestions, will try them. Yes, I mistyped and meant 2.20.59. The problem may be a little strange. I tried Engine Driver 2.20.59 (on Tablet) at the club and it did not suffer the shut-down behavior, however, none of the locos would respond to the throttle after acquiring the loco address. I tried Engine Driver 2.18 (on phone) and 2.20.59 (on Tablet) at home and both worked fine. Both club and home computers are Windows 7 Pro running JMRI 4.12. Two differences that come to mind are:
1.?????? Club computer is interfaced to Digitrax DCS200 using RR-Circuits LocoBuffer-USB. Home computer is interfaced to NCE PowerHouse using Keyspan USB-Serial.
2.?????? Club computer was upgraded to JMRI 4.12 from 4.8. Home computer was upgraded from 4.10.
