Claim:
A method of operating a computer system having a memory system storing word processing software and a processing system for executing said word processing software to control automatic document formatting operations of various types and user-initiated undo operations, said method comprising: monitoring by said processing system whether a user initiated an undo operation while editing a document; determining by said processing system whether said undo operation eliminated a document change caused by an automatic formatting operation of a particular type; monitoring by said processing system information related to undo operation usage with respect to said document including the number of undo operations initiated by said user to undo said particular type of automatic formatting operation; storing in said memory system information indicative of a threshold number of permissible automatic formatting-related undo operations; accessing by said processing system from said memory system said threshold number of permissible automatic formatting-related undo operations; determining by said processing system whether a user initiated undo operation resulted in undo operation use exceeding said threshold number; and disabling said automatic formatting operation of said particular type by said processing system if said threshold number has been exceeded.
