Project Account Paid on Account Balance
Using Clean Up Record on a Project account with a Paid On Account balance would make the problem the worse, by adding a balance during the recalculation, rather than subtracting.
User bug report.
In the Billing Record, turn off or adjust the erroneous Paid On Account item.
Clean Up Record will now actually clean things up properly, in Goldenseal project billing software versions 4.9 and later.
Programmer note: code changed in CProjectAccount::CleanUp. Actually, we were subtracting a negative amount when we should have added it.
