I just loaded JMRI 4.0.1 on the club computers last week and now they have published 4.2. It’s getting hard to keep up with the changes. I’ll have to read any new help files to see what has changed and how to use any new stuff. I finally figured out how to load either of the two setups we use for programming or WiFi throttles. I went to their Yahoo web site and asked about a new printable help file and was told to use the program help file. That’s great if you have two screens to read the help file while you work with the changes. I’ll have to set up my Digitrax laptop with a second screen to practice.
