I have an issue with a panel (lwpanel)
doing a progress bar (similar to laymon2 SDK sample),
a data variable is incremented in a looping function
and the progress bar is updated step by step in the panel
using a RENDER_CON function for this control.

This works well in LW 2018, but no more in LW 2019.
I have also a raster function with same progress effect, which fails too.
Is this related to new version of Raster functions?
