I should have looked at the stack properties as well as global 
properties: the stack's visible property was false.

This is a database stack where most activity is initiated by Library 
handlers that "go invisible" to the database to file a new record. 
The handler causing the problem was running from inside the database 
stack, and needed a show stack statement following the call to the 
Library's record-filing handler.
