Yes, and across all three platforms; it’s a keeper. I have requested that the distribution be changed to install the javafx.xxxx.jar files in the Processing/libraries/javafx/library folder initially so that users won’t have to do it manually.
I never had a problem with this issue on MacOS because I had unwittingly installed all the javafx.xxxx.jar files in the libraries/javafx/library folder to start with. The clincher occurred when I removed all of them from this folder and broke my own system so that it would no longer run JavaFX demos. I then re-installed the javafx.xxxx.jar files in the libraries/javafx/library folder and ‘fixed‘ it.
