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.
