Hello everyone, im new here and new with maya.
I start with maya 1 week ago, with maya 2012 Sp2 x64, and i have a problem in the outliner.

sometimes when i save, close maya, open again. The screen start in blank, everything is in wireframe and i find some Grey shader nodes in my outliner and i cant take it out.



I was reading some post here and i see some people with the same problem...
there is some solution to this? or the problem still there?
