For a custom object, one of my users is unable to change the record type of a record she owns.  The "change" link simply does not appear for her.  It does appear for me as sysadmin.

I've double-checked that her profile has full CRUD permissions on the object, has access to all of the record types, and has field permissions on the Record Type field.  I've also logged in as her in sandbox, and double-checked that she's not just mis-reporting this.

What else would prevent her from being able to change the rectype?

Thanks!
