[v3] Plane back material problem

[Miroku]

Hi everyone!
I've got a problem with the back material of a plane.
There are 4 issues:
1st - when my code is like this
http://pastebin.com/22XnUWaT
I get this result (blue is front, green is back)
http://dl.dropbox.com/u/4064417/flippedBack2.avi
as you see, buttons work but everything is flipped.

2nd: when my code is like this
http://pastebin.com/F23mL4Ja
I get this result (blue is front, green is back)
http://dl.dropbox.com/u/4064417/flippedBackNoButtons.avi
as you see buttons are disappeared ._______.

3rd: when my code is like this:
http://pastebin.com/TRxPdQk4
I get this result (blue is front, green is back)
http://dl.dropbox.com/u/4064417/flippedBackNoFace.avi
no face .___.

4th and last: when I scale the MovieClip directly on the stage I get
this:
http://dl.dropbox.com/u/4064417/flippedBackButtonsDisabled.avi
the movieclip is still flipped wrong and the buttons aren't clickable

what's wrong here? How can I get what I want (a right-flipped and
interactive movieclip)?
