I think I was using 8.1.36 with no issues.
I'm a new user - love the program when it works - but is it possible to have multiple versions saved on my computer? If I find a stable version, I would want to keep that and download the latest version to test.
I'm working on a MAC. Can I just label "TheLightingController" App files as "TheLightingController8.1.36" and then "TheLightingController8.2.4" to have multiple versions?
