V5 Purchase order bug!

In Vantage v4 when you made a chage to a PO the status of the
PO would change from NEW to CHANGED. There is a bug that if
the change is made on the same date of the PO the status flag
is not changed. We've learned to live with that.

However... in v5... any change you make on a PO does not
change the status of the PO from NEW to CHANGED. You must
set this manually.
