I have screens I've make in Scree4. I have made versions for 2, 3, or 4 axes.
If I load a part, it generally highlights where I've already cut only on the current cut path, then it resets clearing the display before moving on to the next cut path. If I change to a different set of screens, I might get no trace at all. AND, if I load the 1024 screens, now it works perfectly.
Who knows. It's not my setup. If it was, it wouldn't work in the 1024 set.
I have a direct email in to Brian, and if he gives me a heads up I'll pass it on.
