Well it kinda does all the time and that's the issue. Sorry for posting it in the CODE format.
Note that the VBA code runs from a normal.dotm template, not the Word document I'm editing.

I think new Word documents are opened in a new instance that isn't included in:
Word.Application.Documents.Count
When I have 3 Word files open the document count is 1. After closing that file the count is 0 and a completely grey window is left. That's closed with
Application.Quit
