Editor unable to find Header Files

[weaver4]

In a new console project the first line is:

#include <QtCore/QCoreApplication>

If I hover over this line the editor says: "No such file or Directory"

If I Build and Run it compiles and runs fine.

It appears that the Editor can not find the header files but the compiler can. Without this working Code Completion does not work.

I am using Qt Creator 2.0.1

What can I do to resolve this?
