Hi,
I've just bought the NGUI 3.9.6b and try to import to unity 5.2.3f1,
after creating a clean project and importing NGUI, there are two error shown and the NGUI menu doesn't shown in tool bar.

Following are the errors.
Assets/NGUI/Scripts/Internal/NGUITools.cs(1493,35): error CS1061: Type `UnityEngine.TextEditor' does not contain a definition for `text' and no extension method `text' of type `UnityEngine.TextEditor' could be found (are you missing a using directive or an assembly reference?)
Assets/NGUI/Scripts/Internal/NGUITools.cs(1502,28): error CS1061: Type `UnityEngine.TextEditor' does not contain a definition for `text' and no extension method `text' of type `UnityEngine.TextEditor' could be found (are you missing a using directive or an assembly reference?)
how to fix it?
Thanks...
