I think I found it! When I added the code to draw a teal Z-plane for certain functions (Support Z-Roof, Sheath Z-Roof, and the [*] N Layers), I tried to only have the teal plane update/show when the user pressed [Enter]. Unfortunately, this means those values only are *stored* when pressing [Enter]. This probably also explains the issue someone else was having with the Support Z-Roof not working as expected.
WORKAROUND: press [Enter] after changing those values.
I'll try to get a release out ASAP.
thanks,
Jonathan
