I've done some more experimenting. OE only freezes up when we try and enter a reference# in the header tab. If I leave it blank, then the order enters fine. We need to enter this, as this is our cutomer's PO# which gets us paid.

This is a high volume customer. Is it possible that it is looking for similar reference numbers?

I noticed that when I tried to enter a reference number in an order for another customer, it asked me if I would like to use the same reference as in document I xxxxxx (it was an invoice). It never use to ask us this.

Any ideas?

Thanks,
