none of the stuff written in http://unity3d.com/support/documentation/Components/gui-Basics.html seems to work.
I get errors saying "'Box' is not a member of 'GUI'." (ans same about Button and everything else), even though the documentation says: "This example is a complete, functional level loader. If you copy/paste this script and attach it a GameObject, you'll see the following menu appear in when you enter Play Mode: " (I just tried the first example on the page)
do you have to "activate" the GUI or something ? or did they change how this works in unity 3 (but haven't changed the docs yet) ?
