The UnregisterExternalWindow transaction unregisters an external window used by Imagenation for rendering either a document, Reference, or Detail external window.
After you register an external window as a document window, you can open a document in it, and perform actions on the document (such as Merge and Save). However, before opening another document in it, you must unregister the external window, and then register it again. If you open and process multiple documents in an external window without registering and unregistering the window each time, you will quickly run out of resources.
