Upgraded a client from 4.30 to 4.50. Problem started after upgrade. Several times when auto generating purchase orders from sales order, the total of the sales order does not match the total of the line items. The correct total is shown on the lines tab, but the totals tab shows a completely incorrect number with no relation to the lines. Could not duplicate, but have seen the result and it has happened multiple times in last 3 weeks. Nothing in knowledgebase.
