Cust. Ledger Remaining Amount Off

We are running Naviosn 4.00 SP2 SQL on a SQL 2005 64bit Server and have a situation where some Customer Legder Entries Remaining Amounts are showing a $0.01 balance even though the Detail Cust. Ledger Entries total up to 0. The Remaining Amount (LCY) is correct and shows a $0.00 but the Remaining Amount is off and then invoice is still open.

Remaining amount can be formatted to display 0,00 but have a value of 0,0001 and consequently balance will display 0,01.
Can you confirm that ?
