In the date field, type "1/1/13". Does it change this to "1/13/2001" for you? Does it change "2/8/13" to "2/13/2008" for you?
If others are experiencing this, to whose attention can this be brought, given that we're talking about a date as near as Tuesday, now?
If it's just me, can any friendly soul suggest where I might start fixing this?
