Moi3d v3 I used CustomUI 1.03 with Dark Gray Theme for 3.0
Moi3d v4 beta I used CustomUI 2.0 Beta 2 with Dark Gray Theme for 4.0 beta

Tried fresh v4 install without dark gray theme and it has the same list problem.
When installing in AppData folder, does all three folders go there? or only startup folder contents?

I've attached screenshots:

v3 Ext Scripts List Works


v3 not sure how lighting script works


v3 Obj Library List Works


v4 Ext Scripts List Both Empty


v4 lighting doesnt show a message


v4 node edit and log button shows empty windows


v4 Obj Library List Empty


v4 subdiv script seems to be missing
