[away3d] Render problem (Z-sorting and plane breaks)

[Ju]

Hi all
i using last away3d from svn and have trouble with z-sorting
take a look image(http://img528.imageshack.us/img528/7465/zsorttrouble.jpg)
for best understanding.
why if the camera is close to plane, plane breaks(1) and what happens
with moon if plane overrides moon(2).

CORRECT_Z_ORDER and INTERSECTING_OBJECTS can't help =(
Сan you help me?
