I've tried all older versions of LW and it seems that LW 2019.0.3 and since 2019 released, the dimension tools don't seem to leave their distances in the viewport any longer.
LightWave version 2018 worked fine.
I have tried deleting all configs and starting from scratch in 2019 and it makes no difference. Also have tried all OpenGL modes to see if that made a difference, but it didn't.
Please can this be fixed in a patch, as I use it frequently.
