Orphan methods can exist, for example, when an object was deleted, but for whatever reason, the corresponding object method was not removed from the structure.

Orphan methods can be revealed by running a repair in the MSC. The method becomes available in the design enviroment and is named "__Orphan###" where "###" is a string of digits.

The developer should go through there database using the Explorer and look through the orphan methods and either delete them or re-use the code elsewhere as necessary.
