Version 18.1.0 Build 625 09/12/2018 SJ Lite Edition (Linux) on Ubuntu 18.04 is working until:
Seems that most MegaFunction do lockup at some point,when an input changes the dialog size. I did try LPM_MUX, changed the number and was allow to progress to the next screen, but locks up after that.
Have the openkdk installed: openjdk 10.0.2 2018-07-17
If the window is enlarged in the horizontal direction there is no lockup.
