"File Locked for Editing By..." has Wrong Name - how?!
You know the "This file is locked for editing by..." message in Office? Well, we've got a weird one here whereby whoever opens a specific file, it says "This file is locked for editing by Mr A" even though Mr B has the file open. If Mr B opens a different file, then it reports correctly that Mr B has it open, so it isn't anything to do with Mr B's settings.
This isn't a major problem, but is bugging me! Plus, it can be annoying if you desperately need that file, so got to Mr A and ask him to close it, then find he doesn't have it open.
