Well, Zero edit doesn't seem to like saving paths, boundaries, sky color (ambient and all that jazz), and alot of times, it flips my models along the red axis.. (yes, I've already put FlipModelX=0 in my ini file)
Does anyone know why? It works fine on my XP, but I don't hardly get to use it. And I'm on windows7
-edit: and nothing is read-only either
Just figured this out.
Solution:
Right click zeroedit.exe, click properties, and under Compatiblity, "Run This program in compatiblity mode for: Windows XP Service pack 3" and appy.
It now saves all the data (including sky colors)
