Previously when I have been browsing NAML code, they all displayed with the navigation links.
Recently I frequently get this message:
The source code below doesn't have navigation links because no usage has been compiled yet. Navigation links depend on how and where the macro is used, so first you may try finding all usages of "<macro name>". And the '
Usages of this macro' link shown nothing.
This initially lead me to think that macro was no longer used anywhere. A red herring.
It is making it difficult to look into NAML issues and/or customisation.
What is causing this?
