[otrs] Phantom Ticket reopening

We are using otrs on a windows 2003 server version 2.0.3 and MySQL. Starting yesterday, an agent reports that every time she closes a ticket it reopens itself with the message: "The state of your ticket "20071100510000038" has been changed by "Admin OTRS" to "open". We have not change anything on the system and the agent is one of the primary long time users - Suggestions welcome Keith
