It has recently been brought to my attention that the SO-A screen (enhanced 10/8/04) has a bug that I can't quite pin down as to the cause, but did witness it happen.  The problem:  sales orders are asking to be closed when there are still lines items to bill.
 
The scenario:  We created a multiple (four) line item sales order, saved it, then reopened it, deleted the last three lines from the order, and then saved it.  The first line item was untouched and remained with items left to bill; however, a dialog box popped up stating that the SO had no line items with unbilled quantities, and asked if we wanted to close it?
 
Seems to occur randomly, but has happened a few times since our last ISTS upgrade.  Any ideas?  ???
